Title
Cisco Identity Services Engine XML External Entity Injection Vulnerabilities
Summary
Multiple vulnerabilities in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to read arbitrary files or conduct a server-side request forgery (SSRF) attack through an affected device. To exploit these vulnerabilities, an attacker must have valid Administrator credentials on the affected device. For more information about these vulnerabilities, see the Details section of this advisory.

Summary
On Feb 15, 2023, the following vulnerability in the ClamAV scanning library was disclosed:
A vulnerability in the DMG file parser of ClamAV versions 1.0.0 and earlier, 0.105.1 and earlier, and 0.103.7 and earlier could allow an unauthenticated, remote attacker to access sensitive information on an affected device.
This vulnerability is due to enabling XML entity substitution that may result in XML external entity injection. An attacker could exploit this vulnerability by submitting a crafted DMG file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to leak bytes from any file that may be read by the ClamAV scanning process.

Title
Cisco Identity Services Engine XML External Entity Injection Vulnerability
Summary
A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to access sensitive information, conduct a server-side request forgery (SSRF) attack through an affected device, or negatively impact the responsiveness of the web-based management interface itself. This vulnerability is due to improper handling of XML External Entity (XXE) entries when parsing certain XML files. An attacker could exploit this vulnerability by uploading a crafted XML file that contains references to external entities. A successful exploit could allow the attacker to retrieve files from the local system, resulting in the disclosure of confidential information. A successful exploit could also cause the web application to perform arbitrary HTTP requests on behalf of the attacker or consume memory resources to reduce the availability of the web-based management interface. To successfully exploit this vulnerability, an attacker would need valid Super Admin or Policy Admin credentials.

This vulnerability is due to improper handling of XML External Entity (XXE) entries when parsing certain XML files. An attacker could exploit this vulnerability by uploading a crafted XML file that contains references to external entities. A successful exploit could allow the attacker to retrieve files from the local system, resulting in the disclosure of confidential information. A successful exploit could also cause the web application to perform arbitrary HTTP requests on behalf of the attacker or consume memory resources to reduce the availability of the web-based management interface. To successfully exploit this vulnerability, an attacker would need valid Super Admin or Policy Admin credentials."

Title
Sangfor Behavior Management System XML External Entity Injection
Summary
Sangfor Behavior Management System (also referred to as DC Management System in Chinese-language documentation) contains an XML external entity (XXE) injection vulnerability in the /src/sangforindex endpoint. A remote unauthenticated attacker can submit crafted XML data containing external entity definitions, leading to potential disclosure of internal files, server-side request forgery (SSRF), or other impacts depending on parser behavior. The vulnerability is due to improper configuration of the XML parser, which allows resolution of external entities without restriction. This product is now integrated into their IAM (Internet Access Management) platform and an affected version range is undefined. Exploitation evidence was first observed by the Shadowserver Foundation on 2023-09-06 UTC.

Summary
In Eclipse Memory Analyzer versions 0.7 to 1.14.0, report definition XML files are not filtered to prohibit
document type definition (DTD) references to external entities.
This means that if a user chooses to use a malicious report definition XML file containing an external entity reference
to generate a report then Eclipse Memory Analyzer may access external files or URLs defined via a DTD in the report definition.

Title
Possible XXE vulnerability in Jenkins Plugin for Qualys Web Application Security
Summary
Qualys Jenkins Plugin for WAS prior to version and including 2.0.11 was identified to be affected by a security flaw, which was missing a permission check while performing a connectivity check to Qualys Cloud Services. This allowed any user with login access to configure or edit jobs to utilize the plugin and configure potential a rouge endpoint via which it was possible to control response for certain request which could be injected with XXE payloads leading to XXE while processing the response data

Mitigation
Implementation
System Configuration
Many XML parsers and validators can be configured to disable external entity expansion.
CAPEC-221: Data Serialization External Entities Blowup
This attack takes advantage of the entity replacement property of certain data serialization languages (e.g., XML, YAML, etc.) where the value of the replacement is a URI. A well-crafted file could have the entity refer to a URI that consumes a large amount of resources to create a denial of service condition. This can cause the system to either freeze, crash, or execute arbitrary code depending on the URI.
