Lifecycle Timeline
4DescriptionGitHub Advisory
WeGIA is a Web manager for charitable institutions. Prior to 3.6.9, the redirect parameter is taken directly from $_GET with no URL validation or whitelist check, then used verbatim in a header("Location: ...") call. This vulnerability is fixed in 3.6.9.
AnalysisAI
Open redirect vulnerability in WeGIA web manager prior to version 3.6.9 allows unauthenticated remote attackers to redirect users to arbitrary external URLs by injecting a malicious redirect parameter into HTTP requests. The vulnerability exploits missing URL validation on the redirect parameter, which is passed directly to PHP's header() function without sanitization or whitelist checks. User interaction is required as the victim must click a crafted link, but successful exploitation can facilitate phishing attacks or credential theft by redirecting users to attacker-controlled domains that masquerade as legitimate institutional websites.
Technical ContextAI
WeGIA is an open-source web management platform for charitable institutions built in PHP. The vulnerability stems from improper handling of user-supplied input in the redirect parameter, which maps to CWE-601 (URL Redirection to Untrusted Site / 'Open Redirect'). The affected code retrieves the redirect parameter from the GET request ($_GET['redirect']) and uses it directly in a PHP header() call without any validation, URL scheme checking, or whitelist comparison. This classic open redirect pattern bypasses browser same-origin policies for HTTP redirection, allowing attackers to craft URLs like 'https://wegia.example.com/?redirect=https://attacker.com' that appear to originate from the legitimate institution domain before redirecting to a malicious site. The vulnerability exists in all versions of WeGIA prior to 3.6.9, as specified by the CPE cpe:2.3:a:labredescefetrj:wegia:*:*:*:*:*:*:*:* indicating all versions below the patched release are affected.
RemediationAI
Vendor-released patch: WeGIA 3.6.9. Affected organizations should upgrade to version 3.6.9 or later immediately. The fix implements proper URL validation and whitelisting of the redirect parameter before use in header() calls. Organizations unable to upgrade immediately should implement a temporary workaround by adding server-side validation logic that whitelists only trusted redirect domains (e.g., only allowing redirects to URLs matching the institution's own domain) or by disabling the redirect feature entirely until patching is completed. Additional mitigation includes content security policy (CSP) headers to restrict untrusted redirect destinations. Refer to the GitHub Security Advisory GHSA-qfpg-6jh6-jx6p for detailed patch information and migration guidance.
