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: None: The vulnerable system can be exploited without interaction from any human user, other than the attacker.
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: Low: Performance is reduced or there are interruptions in resource availability. Even if repeated exploitation of the vulnerability is possible, the attacker does not have the ability to completely deny service to legitimate users. The resources in the Vulnerable System are either partially available all of the time, or fully available only some of the time, but overall there is no direct, serious consequence to the Vulnerable System.
Subsequent system confidentiality: None: There is no loss of confidentiality within the Subsequent System or all confidentiality impact is constrained to the Vulnerable System.
Subsequent system integrity: None: There is no loss of integrity within the Subsequent System or all integrity impact is constrained to the Vulnerable 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.

Exploitation evidence

Disclosed: evidence found.
CVE published 5 Jun 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
Observed by OffSeq MirageSeen by Mirage: no evidence on record.
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 2026-10-26.

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

European organizations should immediately audit their use of PHPGurukul Complaint Management System 2.0 and assess exposure of the /admin/manage-users.php endpoint. Specific mitigations include: 1) Implementing strict input validation and parameterized queries or prepared statements to prevent SQL injection in the 'uid' parameter. 2) Restricting access to the admin interface via network controls such as VPNs, IP whitelisting, or firewall rules to limit exposure to trusted users only. 3) Monitoring web server and application logs for unusual or suspicious requests targeting the 'uid' parameter. 4) Applying web application firewalls (WAFs) with rules to detect and block SQL injection attempts targeting this endpoint. 5) If possible, upgrading to a patched or newer version of the software once available. 6) Conducting a thorough security review of all input handling in the application to identify and remediate similar vulnerabilities. 7) Ensuring regular backups of complaint data to enable recovery in case of data tampering or loss.

Description

A vulnerability was found in PHPGurukul Complaint Management System 2.0. It has been rated as critical. This issue affects some unknown processing of the file /admin/manage-users.php. The manipulation of the argument uid leads to sql injection. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used.

Impact

For European organizations using PHPGurukul Complaint Management System 2.0, this vulnerability poses a significant risk to the confidentiality and integrity of complaint and user data. Exploitation could lead to unauthorized access to sensitive personal information, which may include customer complaints, user identities, and possibly other linked data. This can result in data breaches with regulatory consequences under GDPR, including heavy fines and reputational damage. Additionally, attackers could manipulate or delete complaint records, undermining trust in the complaint management process and potentially disrupting business operations. The remote and unauthenticated nature of the exploit increases the risk of automated attacks, especially if the system is exposed to the internet. Given the critical role complaint management systems play in customer service and compliance, exploitation could also impact service availability and organizational responsiveness.
