Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: Required: Successful exploitation of this vulnerability requires a user to take some action before the vulnerability can be exploited.
Scope: Changed: An exploited vulnerability can affect resources beyond the security scope managed by the security authority of the vulnerable component. In this case, the vulnerable component and the impacted component are different and managed by different security authorities.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: Low: Modification of data is possible, but the attacker does not have control over the consequence of a modification, or the amount of modification is limited. The data modification does not have a direct, serious impact on the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

Disclosed: evidence found.
CVE published 14 Jul 2025
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-25.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

AI-suggested

To mitigate this vulnerability, European organizations should immediately upgrade WeGIA installations to version 3.4.5 or later, where the issue is patched. If immediate upgrading is not feasible, organizations should implement strict input validation on the 'nextPage' parameter, restricting redirects to a whitelist of trusted internal URLs only. Web application firewalls (WAFs) can be configured to detect and block suspicious redirect patterns targeting the vulnerable endpoint. Additionally, organizations should educate users about the risks of clicking on unexpected links, especially those that appear to redirect through trusted domains. Monitoring logs for unusual redirect requests can help identify attempted exploitation. Finally, integrating multi-factor authentication (MFA) can reduce the impact of phishing attacks that might leverage this vulnerability to steal credentials.

Description

WeGIA is an open source web manager with a focus on the Portuguese language and charitable institutions. An Open Redirect vulnerability exists in the web application prior to version 3.4.5. The control.php endpoint allows to specify an arbitrary URL via the `nextPage` parameter, leading to an uncontrolled redirection. Version 3.4.5 contains a fix for the issue.

Impact

For European organizations using WeGIA, particularly charitable institutions and entities operating in Portuguese-speaking communities within Europe, this vulnerability poses a moderate risk. The primary impact is on user trust and potential phishing attacks leveraging the open redirect to redirect users to malicious sites that could harvest credentials or distribute malware. While the vulnerability does not directly compromise system confidentiality or availability, it can be used as a stepping stone in social engineering attacks or combined with other vulnerabilities for more severe consequences. Organizations relying on WeGIA for managing web content or user workflows may see reputational damage if users fall victim to redirected phishing scams. Additionally, regulatory frameworks such as GDPR emphasize protecting users from phishing and fraud, so exploitation could lead to compliance issues. The risk is heightened in environments where users are less security-aware or where the application is integrated into critical user-facing portals.

CWE-601URL Redirection to Untrusted Site ('Open Redirect') (opens in a new tab)
Base weaknessLikelihood of exploit: LowOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The web application accepts a user-controlled input that specifies a link to an external site, and uses that link in a redirect.
Implementation · 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.
Architecture and Design
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.
Architecture and Design · 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.
