CVE-2025-7791 is a medium-severity Cross Site Scripting (XSS) vulnerability identified in version 1.0 of the PHPGurukul Online Security Guards Hiring System. The vulnerability resides in the /admin/search.php file, specifically in the handling of the 'searchdata' parameter. An attacker can remotely manipulate this parameter to inject malicious scripts, which are then executed in the context of the victim's browser. This type of vulnerability allows attackers to perform actions such as session hijacking, defacement, or redirecting users to malicious sites. The vulnerability does not require authentication (PR:L indicates low privileges, but the vector is network-based with no authentication needed), but it does require some user interaction (UI:P), meaning the victim must interact with a crafted link or input. The CVSS 4.0 vector indicates no impact on confidentiality (VC:N), low impact on integrity (VI:L), and no impact on availability (VA:N). The exploitability is rated as partially functional (E:P), and the attack complexity is low (AC:L). No patches have been published yet, and no known exploits are reported in the wild, but the exploit details have been publicly disclosed, increasing the risk of exploitation. The vulnerability affects only version 1.0 of this specific product, which is a niche application used for hiring security guards online. The lack of authentication requirement and remote exploitability make this a notable risk for administrators and users of this system, especially in administrative interfaces where sensitive data or controls may be exposed.

For European organizations using the PHPGurukul Online Security Guards Hiring System 1.0, this vulnerability could lead to unauthorized script execution in the context of administrative users. This could result in session hijacking, unauthorized actions within the admin panel, or redirection to malicious sites, potentially compromising the integrity of the hiring system and exposing sensitive personnel or operational data. While the impact on confidentiality is low, the integrity of the system and trustworthiness of the administrative interface could be undermined. This could disrupt hiring operations or lead to reputational damage if attackers leverage the vulnerability for phishing or spreading malware. Given that the vulnerability requires user interaction, the risk is higher if administrative users are targeted with crafted links or emails. The absence of known exploits in the wild currently limits immediate risk, but public disclosure increases the likelihood of future exploitation attempts. Organizations relying on this system should consider the potential operational impact and the risk of lateral movement if attackers gain foothold through this vector.

1. Immediate mitigation should include restricting access to the /admin/search.php page to trusted IP addresses or VPNs to reduce exposure. 2. Implement strict input validation and output encoding on the 'searchdata' parameter to neutralize malicious scripts. 3. Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts in the browser context. 4. Educate administrative users about phishing risks and the dangers of clicking on untrusted links, especially those targeting the hiring system. 5. Monitor web server logs for unusual requests to the vulnerable endpoint and signs of attempted exploitation. 6. If possible, isolate the hiring system from other critical infrastructure to prevent lateral movement. 7. Engage with the vendor or development team to obtain or develop a patch addressing the vulnerability. 8. Consider deploying Web Application Firewalls (WAFs) with rules to detect and block XSS payloads targeting the affected parameter. 9. Regularly review and update administrative access controls and session management policies to minimize the impact of potential session hijacking.
