GHSA-VP58-J275-797X
Vulnerability from github – Published: 2025-02-24 20:49 – Updated: 2025-12-09 16:27Summary
A bypass was discovered in the trustedOrigins validation logic—affecting both absolute URL entries and wildcard domain patterns. This flaw allows an attacker to construct a malicious callbackURL that passes origin checks and triggers an open redirect.
Because redirect endpoints include sensitive tokens (such as password-reset tokens), this vulnerability can enable one-click account takeover if a victim clicks a crafted link.

Vulnerability from github – Published: 2024-05-23 17:12 – Updated: 2024-05-23 17:12A vulnerability has been found in the SilverStripe framework where a login url can be potentially redirected to an external site.
For example, the url http://www.my-silverstripe-site.com/Security/login?BackURL=/\attacker-site.com will redirect successful logins to the page http://attacker-site.com. If that website were set up to look identical to the first with "login failed" then the user will likely just enter their user/pass again.

GHSA-VPXM-CR3R-PJP9
Vulnerability from github – Published: 2025-01-30 17:50 – Updated: 2025-01-30 17:50Impact
We recently underwent Penetration Testing of OpenMRS by a third-party company. Vulnerabilities were found, and fixes have been made and released. We've released security updates that include critical fixes, and so, we strongly recommend upgrading affected modules.
This notice applies to all OpenMRS instances. The testers used the OpenMRS v3 Reference Application (O3 RefApp); however, their findings highlighted modules commonly used in older OpenMRS applications, including the O2 RefApp.
Vulnerability Details
- The issues uncovered included broken access control (e.g. inappropriate admin access), phishing vulnerability, and stored XSS (e.g. vulnerable passwords).
- No vulnerabilities were found in the O3 frontend esm modules.
- The Letter of Attestation from the penetration test is available here for your reference.
- After the fixes were applied, the OpenMRS O3 RefApp met a Security Level of “Excellent, Grade A”.
- The full detailed Remediation Pentest Report is available to Implementation Technical Leads upon request.
Patches
Minimum Requirements for Implementers: We strongly recommend upgrading your modules to the following versions (or greater) as soon as possible. This is the minimum amount to do and be protected from the vulnerabilities found and fixed. The following versions contain the patch:
- Platform 2.6.11+
- How: Increase your platform version number wherever this is specified in your implementation. If you use the OpenMRS SDK, this will be in the distro.properties file.
- Notes:
- The newly released Platform 2.7 also includes the fixes. Release Notes and more download options here.
- Platform 2.6.8+ has most of the fixes, but these are broken if you don't use SSL, so Platform 2.6.11 or higher is preferred.
- For those still on Platform 2.5+ such as the Bahmni ecosystem, the new 2.5.14 release includes the patch. Bahmni note: The upcoming patch release for both Bahmni Lite and Bahmni Standard will incorporate these security fixes.
- Legacy UI OMOD 1.21.0+ (here)
- ID Gen OMOD 4.14.0+ (here)
- Address Hierarchy OMOD 2.19.0+ (here)
- Attachments OMOD 3.6.0+ (here)
- Patient Flags OMOD 3.0.8+ (here)
Workarounds
There are no practical workarounds to fix or remediate the vulnerabilities without upgrading. Technically, you could remove the affected OMODs, but this would badly degrade the system's functionality.
Thank you to our amazing Security contributors!
Thank you to security firm UnderDefense, and to the OpenMRS Security Group contributors for their patch support - specific thanks to Daniel Kayiwa, Samuel Lubwama, Ian Bacher, Rafal Korytkowski, and Michael Seaton.

[Release Notes and more download options here](https://openmrs.atlassian.net/wiki/x/XoBzEQ).\n - Platform 2.6.8+ has most of the fixes, but these are broken if you don\u0027t use SSL, so Platform 2.6.11 or higher is preferred.\n - For those still on Platform 2.5+ such as the Bahmni ecosystem, the new [2.5.14](https://ci.openmrs.org/browse/TRUNK-CORE2-232) release includes the patch. _Bahmni note: The upcoming patch release for both Bahmni Lite and Bahmni Standard will incorporate these security fixes._\n- **Legacy UI** OMOD 1.21.0+ ([here](https://addons.openmrs.org/show/org.openmrs.module.legacyui))\n- **ID Gen** OMOD 4.14.0+ ([here](https://addons.openmrs.org/show/org.openmrs.module.idgen))\n- **Address Hierarchy** OMOD 2.19.0+ ([here](https://addons.openmrs.org/show/org.openmrs.module.addresshierarchy))\n- **Attachments** OMOD 3.6.0+ ([here](https://addons.openmrs.org/show/org.openmrs.module.attachments))\n- **Patient Flags** OMOD 3.0.8+ ([here](https://addons.openmrs.org/show/org.openmrs.module.patientflags))\n\n### Workarounds\nThere are no practical workarounds to fix or remediate the vulnerabilities without upgrading. Technically, you could remove the affected OMODs, but this would badly degrade the system\u0027s functionality.\n\n## Thank you to our amazing Security contributors!\nThank you to security firm UnderDefense, and to the OpenMRS Security Group contributors for their patch support - specific thanks to Daniel Kayiwa, Samuel Lubwama, Ian Bacher, Rafal Korytkowski, and Michael Seaton. \n",

Mitigation MIT-5
Strategy: Input Validation
- Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
- When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
- Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
- Use a list of approved URLs or domains to be used for redirection.
Mitigation
Use an intermediate disclaimer page that provides the user with a clear warning that they are leaving the current site. Implement a long timeout before the redirect occurs, or force the user to click on the link. Be careful to avoid XSS problems (CWE-79) when generating the disclaimer page.
Mitigation MIT-21.2
Strategy: Enforcement by Conversion
- When the set of acceptable objects, such as filenames or URLs, is limited or known, create a mapping from a set of fixed input values (such as numeric IDs) to the actual filenames or URLs, and reject all other inputs.
- For example, ID 1 could map to "/login.asp" and ID 2 could map to "http://www.example.com/". Features such as the ESAPI AccessReferenceMap [REF-45] provide this capability.
Mitigation
Ensure that no externally-supplied requests are honored by requiring that all redirect requests include a unique nonce generated by the application [REF-483]. Be sure that the nonce is not predictable (CWE-330).
Mitigation MIT-6
Strategy: Attack Surface Reduction
- Understand all the potential areas where untrusted inputs can enter your software: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide data to the application. Remember that such inputs may be obtained indirectly through API calls.
- Many open redirect problems occur because the programmer assumed that certain inputs could not be modified, such as cookies and hidden form fields.
Mitigation MIT-29
Strategy: Firewall
Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth [REF-1481].
CAPEC-178: Cross-Site Flashing
An attacker is able to trick the victim into executing a Flash document that passes commands or calls to a Flash player browser plugin, allowing the attacker to exploit native Flash functionality in the client browser. This attack pattern occurs where an attacker can provide a crafted link to a Flash document (SWF file) which, when followed, will cause additional malicious instructions to be executed. The attacker does not need to serve or control the Flash document. The attack takes advantage of the fact that Flash files can reference external URLs. If variables that serve as URLs that the Flash application references can be controlled through parameters, then by creating a link that includes values for those parameters, an attacker can cause arbitrary content to be referenced and possibly executed by the targeted Flash application.
