Title
Blind SQL Injection in Quick.CMS
Summary
A Blind SQL injection vulnerability has been identified in Quick.CMS. Improper neutralization of input provided by a high-privileged user into multiple fields in administration panel allows for Blind SQL Injection attacks.
The vendor states that this administration panel already allows for significant modification capabilities. The SQL injection vulnerability primarily enables bypassing front-end validation controls and potential database destruction. Given the trust model in which this application is designed to be administered, remediation of this issue was not deemed necessary by the vendor.
This vulnerability has been found in version 6.8, but other versions might also be vulnerable.

Title
Hard-coded admin credentials in Quick.Cart
Summary
Quick.Cart stores hard-coded, plaintext admin credentials in a configuration file. This flaw allows attackers with access to the server file system to retrieve authentication details, potentially leading to privilege escalation.
The vendor assessed the likelihood of exploitation as very low and determined that a fix is not necessary.
Only version 6.7 was tested but all versions should be considered as vulnerable.

Title
Path Traversal in Quick.CMS
Summary
A Path Traversal vulnerability exists in Quick.CMS through the URI path component of HTTP requests, where the server fails to normalize dot-dot-slash (../) sequences before resolving and serving the requested file. An authenticated attacker with admin privileges can use this vulnerability to read contents of files located in the sibling directory of the webroot via a crafted HTTP request containing ../ sequences in the URI.
The vendor assessed the likelihood of exploitation as very low and determined that a fix is not necessary.

Title
Local File Inclusion in Quick.CMS
Summary
Quick.CMS is vulnerable to Local File Inclusion (LFI) in the admin.php endpoint via the p parameter. An authenticated attacker with admin privileges can include arbitrary files located within the application's directory structure via a crafted HTTP request. Successful exploitation allows disclosure of the server's directory structure and absolute file paths (path disclosure).
The vendor assessed the likelihood of exploitation as very low and determined that a fix is not necessary.

Title
Denial of Service in Quick.CMS
Summary
In Quick.CMS, the administrative user interface restricts deletion of the primary language by omitting the corresponding option from the interface; however, the underlying language-deletion API endpoint does not enforce an equivalent server-side authorization check. As a result, an authenticated administrator can bypass the UI-level restriction and delete the primary language by sending a direct HTTP request to the API endpoint. Successful deletion of the primary language results in a Denial of Service (DoS) of application.
Critically, when combined with a separate Cross-Site Request Forgery (CSRF) vulnerability (CVE-2026-1468) an unauthenticated remote attacker can craft a malicious link, which if visited by an authenticated administrator, will trigger the DoS condition without direct access to the application
The vendor assessed the likelihood of exploitation as very low and determined that a fix is not necessary.

Title
Insecure Deserialisation via Plaintext HTTP leading to Remote Code Execution in Quick.CMS
Summary
Quick.CMS deserializes user-controlled data received over plaintext HTTP without ensuring integrity or authenticity. This allows attackers to tamper with serialized payloads in transit and inject malicious objects. Because deserialization is performed without proper validation or class restrictions, crafted payloads can trigger dangerous magic methods (e.g., __wakeup() and __destruct()) and leverage gadget chains, resulting in arbitrary code execution. Exploitation is triggered automatically when an administrator accesses the admin panel.
When successfully exploited, this vulnerability allows attackers to execute arbitrary code on the server via manipulated serialized data transmitted over an unprotected channel.
This issue was mitigated by limiting the communication to HTTPS in a patch for version 6.8 published on 14.05.2026, deployments without this patch remain vulnerable.

Title
XSS in QuickCMS
Summary
QuickCMS is vulnerable to Cross-Site Scripting (XSS) through its insecure HTTP-based plugin‑fetching mechanism. A malicious attacker can perform a Man‑in‑the‑Middle (MITM) attack by impersonating the opensolution.org server and serving arbitrary HTML or JavaScript at the plugin list endpoint. When a user accesses the plugin page, the malicious content is automatically fetched, rendered, and executed.
This issue was fixed in a patch to version 6.8 published on 15.05.2026, deployments without this patch are still vulnerable.

Title
Session Fixation in QuickCMS
Summary
QuickCMS allows a user's session identifier to be set before authentication. The value of this session ID stays the same after authentication. This behaviour enables an attacker to fix a session ID
for a victim and later hijack the authenticated session.
This issue was fixed in a patch to version 6.8 published on 15.05.2026, deployments without this patch are still vulnerable.

Title
Session Fixation in Quick.Cart
Summary
Quick.Cart allows a user's session identifier to be set before authentication. The value of this session ID stays the same after authentication. This behaviour enables an attacker to fix a session ID
for a victim and later hijack the authenticated session.
The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.7 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

Title
Remote Code Execution via Local File Inclusion in Quick.Cart
Summary
Quick.Cart is vulnerable to Local File Inclusion and Path Traversal issues in the theme selection mechanism. Quick.Cart allows a privileged user to upload arbitrary file contents while only validating the filename extension. This allows an attacker to include and execute uploaded PHP code, resulting in Remote Code Execution on the server.
The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.7 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

Title
Blind SQL Injection in Quick.CMS
Summary
A Blind SQL injection vulnerability has been identified in Quick.CMS. Improper neutralization of input provided by a high-privileged user into multiple fields in administration panel allows for Blind SQL Injection attacks.
The vendor states that this administration panel already allows for significant modification capabilities. The SQL injection vulnerability primarily enables bypassing front-end validation controls and potential database destruction. Given the trust model in which this application is designed to be administered, remediation of this issue was not deemed necessary by the vendor.
This vulnerability has been found in version 6.8, but other versions might also be vulnerable.

Title
Hard-coded admin credentials in Quick.Cart
Summary
Quick.Cart stores hard-coded, plaintext admin credentials in a configuration file. This flaw allows attackers with access to the server file system to retrieve authentication details, potentially leading to privilege escalation.
The vendor assessed the likelihood of exploitation as very low and determined that a fix is not necessary.
Only version 6.7 was tested but all versions should be considered as vulnerable.

Title
Path Traversal in Quick.CMS
Summary
A Path Traversal vulnerability exists in Quick.CMS through the URI path component of HTTP requests, where the server fails to normalize dot-dot-slash (../) sequences before resolving and serving the requested file. An authenticated attacker with admin privileges can use this vulnerability to read contents of files located in the sibling directory of the webroot via a crafted HTTP request containing ../ sequences in the URI.
The vendor assessed the likelihood of exploitation as very low and determined that a fix is not necessary.

Title
Local File Inclusion in Quick.CMS
Summary
Quick.CMS is vulnerable to Local File Inclusion (LFI) in the admin.php endpoint via the p parameter. An authenticated attacker with admin privileges can include arbitrary files located within the application's directory structure via a crafted HTTP request. Successful exploitation allows disclosure of the server's directory structure and absolute file paths (path disclosure).
The vendor assessed the likelihood of exploitation as very low and determined that a fix is not necessary.

Title
Denial of Service in Quick.CMS
Summary
In Quick.CMS, the administrative user interface restricts deletion of the primary language by omitting the corresponding option from the interface; however, the underlying language-deletion API endpoint does not enforce an equivalent server-side authorization check. As a result, an authenticated administrator can bypass the UI-level restriction and delete the primary language by sending a direct HTTP request to the API endpoint. Successful deletion of the primary language results in a Denial of Service (DoS) of application.
Critically, when combined with a separate Cross-Site Request Forgery (CSRF) vulnerability (CVE-2026-1468) an unauthenticated remote attacker can craft a malicious link, which if visited by an authenticated administrator, will trigger the DoS condition without direct access to the application
The vendor assessed the likelihood of exploitation as very low and determined that a fix is not necessary.

Title
Insecure Deserialisation via Plaintext HTTP leading to Remote Code Execution in Quick.CMS
Summary
Quick.CMS deserializes user-controlled data received over plaintext HTTP without ensuring integrity or authenticity. This allows attackers to tamper with serialized payloads in transit and inject malicious objects. Because deserialization is performed without proper validation or class restrictions, crafted payloads can trigger dangerous magic methods (e.g., __wakeup() and __destruct()) and leverage gadget chains, resulting in arbitrary code execution. Exploitation is triggered automatically when an administrator accesses the admin panel.
When successfully exploited, this vulnerability allows attackers to execute arbitrary code on the server via manipulated serialized data transmitted over an unprotected channel.
This issue was mitigated by limiting the communication to HTTPS in a patch for version 6.8 published on 14.05.2026, deployments without this patch remain vulnerable.

Title
XSS in QuickCMS
Summary
QuickCMS is vulnerable to Cross-Site Scripting (XSS) through its insecure HTTP-based plugin‑fetching mechanism. A malicious attacker can perform a Man‑in‑the‑Middle (MITM) attack by impersonating the opensolution.org server and serving arbitrary HTML or JavaScript at the plugin list endpoint. When a user accesses the plugin page, the malicious content is automatically fetched, rendered, and executed.
This issue was fixed in a patch to version 6.8 published on 15.05.2026, deployments without this patch are still vulnerable.

Title
Session Fixation in QuickCMS
Summary
QuickCMS allows a user's session identifier to be set before authentication. The value of this session ID stays the same after authentication. This behaviour enables an attacker to fix a session ID
for a victim and later hijack the authenticated session.
This issue was fixed in a patch to version 6.8 published on 15.05.2026, deployments without this patch are still vulnerable.

Title
Session Fixation in Quick.Cart
Summary
Quick.Cart allows a user's session identifier to be set before authentication. The value of this session ID stays the same after authentication. This behaviour enables an attacker to fix a session ID
for a victim and later hijack the authenticated session.
The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.7 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.

Title
Remote Code Execution via Local File Inclusion in Quick.Cart
Summary
Quick.Cart is vulnerable to Local File Inclusion and Path Traversal issues in the theme selection mechanism. Quick.Cart allows a privileged user to upload arbitrary file contents while only validating the filename extension. This allows an attacker to include and execute uploaded PHP code, resulting in Remote Code Execution on the server.
The vendor was notified early about this vulnerability, but didn't respond with the details of vulnerability or vulnerable version range. Only version 6.7 was tested and confirmed as vulnerable, other versions were not tested and might also be vulnerable.
