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

Attack Vector: Network: The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, 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: The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Attack Requirements: None: The successful attack does not depend on the deployment and execution conditions of the vulnerable system. The attacker can expect to be able to reach the vulnerability and execute the exploit under all or most instances of the vulnerability.
Privileges Required: Low: The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
User Interaction: Active: Successful exploitation of this vulnerability requires a targeted user to perform specific, conscious interactions with the vulnerable system and the attacker’s payload, or the user’s interactions would actively subvert protection mechanisms which would lead to exploitation of the vulnerability.
Vulnerable system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Vulnerable System.
Vulnerable system 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 to the Vulnerable System.
Vulnerable system availability: None: There is no impact to availability within the Vulnerable System.
Subsequent system confidentiality: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the Subsequent System.
Subsequent system 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 to the Subsequent System.
Subsequent system availability: None: There is no impact to availability within the Subsequent System or all availability impact is constrained to the Vulnerable System.

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 26 Oct 2026.

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 or the CVSS exploit maturity 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

Organizations should immediately upgrade WeGIA to version 3.5.0 or later, where the vulnerability is patched. Until the upgrade is applied, administrators should implement strict input validation and sanitization on the nextPage parameter, possibly by restricting redirects to a whitelist of trusted internal URLs. Additionally, deploying web application firewalls (WAFs) with rules to detect and block suspicious redirect patterns can reduce risk. User awareness training focused on recognizing phishing attempts and suspicious URLs is critical to mitigate the social engineering aspect of this vulnerability. Monitoring web logs for unusual redirect requests and suspicious user activity can help detect exploitation attempts early. Finally, organizations should review and update their incident response plans to address potential phishing or malware incidents stemming from this vulnerability.

Description

WeGIA is an open source web manager with a focus on charitable institutions. Versions 3.4.12 and below contain an Open Redirect vulnerability, identified in the control.php endpoint, specifically in the nextPage parameter (metodo=listarUmnomeClasse=FuncionarioControle). This vulnerability allows attackers to redirect users to arbitrary external domains, enabling phishing campaigns, malicious payload distribution, or user credential theft. This issue is fixed in version 3.5.0.

Impact

For European organizations, especially charitable institutions using WeGIA versions prior to 3.5.0, this vulnerability poses a risk of successful phishing campaigns and malware distribution. Attackers can exploit the open redirect to trick users into visiting malicious sites that may harvest credentials or deliver malicious payloads, potentially leading to data breaches or system compromise. While the direct impact on system integrity and availability is low, the indirect consequences through social engineering can be severe, including reputational damage and financial loss. Given the widespread use of open-source management tools in the nonprofit sector across Europe, organizations with limited cybersecurity resources are particularly vulnerable. The vulnerability's exploitation could also undermine trust in digital services provided by these institutions.

Summary

CVE-2025-61606 is an Open Redirect vulnerability classified under CWE-601 found in the open-source web management software WeGIA, which targets charitable institutions. The vulnerability exists in versions 3.4.12 and earlier, specifically within the control.php endpoint where the nextPage parameter is improperly validated. An attacker can craft a URL that manipulates this parameter to redirect users to arbitrary external domains without proper sanitization or validation. This redirection can be exploited to conduct phishing attacks by luring users to malicious websites, distribute malware payloads, or steal user credentials by impersonating legitimate services. The vulnerability does not require any authentication, making it accessible to unauthenticated attackers, but it does require user interaction to click on the malicious link. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:L), user interaction required (UI:A), and low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:N). The vulnerability has been addressed in WeGIA version 3.5.0, which includes proper validation and sanitization of the nextPage parameter to prevent open redirects. No known exploits are currently reported in the wild, but the risk remains significant due to the potential for social engineering attacks leveraging this flaw.

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.
