CVE-2025-61255 identifies a Cross-Site Scripting (XSS) vulnerability in the Bank Locker Management System developed by PHPGurukul. The vulnerability resides in the /search parameter, which fails to properly sanitize user-supplied input, allowing attackers to inject arbitrary HTML and JavaScript code. This type of vulnerability can be exploited by crafting malicious URLs or input fields that, when processed by the vulnerable system, execute attacker-controlled scripts in the context of the victim's browser session. The consequences include information disclosure, such as theft of session cookies or sensitive data displayed on the page, and user redirection to malicious sites, facilitating phishing or malware distribution. The vulnerability does not require authentication or user interaction beyond visiting a crafted URL, increasing its exploitation potential. No CVSS score has been assigned yet, and no public exploits are known, but the risk remains significant given the nature of XSS attacks. The lack of affected version details suggests the vulnerability may impact all current versions of the system. The Bank Locker Management System is likely used by financial institutions to manage secure storage services, making the confidentiality and integrity of data critical. The vulnerability's exploitation could undermine user trust and lead to regulatory compliance issues, especially under GDPR in Europe.

For European organizations, particularly banks and financial service providers using the Bank Locker Management System by PHPGurukul, this XSS vulnerability poses a serious risk to data confidentiality and integrity. Attackers could steal session tokens, enabling unauthorized access to user accounts or sensitive information. The ability to redirect users to malicious sites increases the risk of phishing attacks targeting customers or employees. Such incidents could result in financial loss, reputational damage, and regulatory penalties under GDPR due to inadequate protection of personal data. The vulnerability's ease of exploitation without authentication or user interaction broadens the attack surface, potentially affecting a large number of users. Additionally, compromised systems could be used as footholds for further attacks within the organization's network. The lack of a patch or mitigation guidance at this time increases the urgency for organizations to implement compensating controls.

Organizations should immediately implement strict input validation and output encoding on the /search parameter to neutralize malicious scripts. Employing a robust Content Security Policy (CSP) can help restrict the execution of unauthorized scripts and reduce the impact of any injected code. Web Application Firewalls (WAFs) should be configured to detect and block XSS attack patterns targeting the vulnerable parameter. Regular security assessments and code reviews should be conducted to identify and remediate similar vulnerabilities. User education on phishing risks and suspicious links can reduce the success of social engineering attacks leveraging this vulnerability. Monitoring web server logs for unusual query strings or repeated attempts to exploit the /search parameter can provide early detection. Until an official patch is released by PHPGurukul, these measures are critical to reduce exposure. Organizations should also engage with the vendor for timely updates and consider isolating or restricting access to the affected system where feasible.
