CVE-2024-51054 is a Cross-Site Scripting (XSS) vulnerability identified in the PHPGurukul Online Marriage Registration System version 1.0, specifically within the /omrs/admin/search.php script. The vulnerability arises from improper sanitization of the 'searchdata' POST parameter, allowing an authenticated attacker with high privileges to inject malicious scripts. This injection can lead to arbitrary code execution within the context of the administrator's browser session, potentially enabling theft of sensitive information, session hijacking, or manipulation of the web interface. The vulnerability requires the attacker to be authenticated and to interact with the system, limiting its ease of exploitation. The CVSS 3.1 base score is 4.8, reflecting a medium severity level, with attack vector being network-based, low attack complexity, but requiring privileges and user interaction. The scope is changed, indicating that the vulnerability affects components beyond the initially vulnerable code. No patches or known exploits have been reported at the time of publication. This vulnerability is classified under CWE-79, which covers improper neutralization of input during web page generation. The lack of a patch necessitates immediate mitigation through input validation, output encoding, and access control measures.

The primary impact of CVE-2024-51054 is the potential compromise of confidentiality and integrity within the PHPGurukul Online Marriage Registration System's administrative interface. An attacker exploiting this vulnerability could execute arbitrary scripts in the context of an authenticated administrator, leading to session hijacking, unauthorized data access, or manipulation of administrative functions. While availability is not directly affected, the integrity of the system's data and the confidentiality of sensitive user information could be at risk. Organizations relying on this system for marriage registration processes may face data breaches or unauthorized administrative actions. The requirement for authentication and user interaction reduces the likelihood of widespread automated exploitation but does not eliminate targeted attacks. The absence of known exploits in the wild suggests limited current impact, but the vulnerability remains a significant risk if left unaddressed.

To mitigate CVE-2024-51054, organizations should implement strict input validation and output encoding on the 'searchdata' POST parameter to prevent script injection. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in the administrative interface. Limit access to the /omrs/admin/search.php endpoint to trusted administrators only, using network segmentation and strong authentication mechanisms such as multi-factor authentication (MFA). Monitor web server logs and application behavior for unusual activity indicative of exploitation attempts. Since no official patch is available, consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block malicious payloads targeting this parameter. Regularly review and update the software to newer versions if available, and engage with the vendor for patch releases. Additionally, conduct security awareness training for administrators to recognize phishing or social engineering attempts that could facilitate exploitation.
