CVE-2022-43097: n/a in n/a
Phpgurukul User Registration & User Management System v3.0 was discovered to contain multiple stored cross-site scripting (XSS) vulnerabilities via the firstname and lastname parameters of the registration form & login pages.
AI Analysis
Technical Summary
CVE-2022-43097 is a medium-severity vulnerability affecting the Phpgurukul User Registration & User Management System version 3.0. The vulnerability consists of multiple stored cross-site scripting (XSS) flaws found in the firstname and lastname parameters of the registration and login pages. Stored XSS occurs when malicious scripts injected by an attacker are permanently stored on the target server and later executed in the browsers of users who access the affected pages. In this case, the lack of proper input validation and output encoding on these user-supplied fields allows attackers to inject arbitrary JavaScript code. When other users or administrators view the affected pages, the malicious scripts execute in their browsers, potentially leading to session hijacking, credential theft, defacement, or further exploitation of the application. The CVSS 3.1 base score of 5.4 reflects a medium severity, with an attack vector of network (remote exploitation), low attack complexity, requiring privileges (PR:L) and user interaction (UI:R). The scope is changed (S:C), indicating that the vulnerability affects resources beyond the vulnerable component. The impact on confidentiality and integrity is low, while availability is not affected. No known exploits in the wild have been reported, and no official patches or vendor information are currently available. The vulnerability is categorized under CWE-79, which is the standard classification for cross-site scripting issues. Given the nature of the vulnerability, attackers could leverage it to perform targeted attacks against users of the system, especially administrators or privileged users, potentially escalating their access or stealing sensitive information.
Potential Impact
For European organizations using the Phpgurukul User Registration & User Management System v3.0, this vulnerability poses a moderate risk primarily to the confidentiality and integrity of user data. Stored XSS can lead to session hijacking, enabling attackers to impersonate legitimate users, including administrators, which could result in unauthorized access to sensitive information or administrative functions. This can further lead to data breaches or manipulation of user accounts. Although availability is not directly impacted, the reputational damage and potential regulatory consequences under GDPR for data breaches involving personal data could be significant. Organizations relying on this system for user management, especially those with large user bases or handling sensitive personal data, are at increased risk. The need for user interaction and privileges to exploit the vulnerability somewhat limits the attack surface but does not eliminate it, particularly in environments where users have elevated privileges or where social engineering could be used to trick users into triggering the malicious payloads. The absence of patches increases the risk of exploitation over time, especially if attackers develop proof-of-concept exploits. Given the interconnected nature of European IT infrastructures, a successful attack could also facilitate lateral movement within networks.
Mitigation Recommendations
1. Immediate implementation of strict input validation and output encoding on all user-supplied data fields, especially firstname and lastname parameters, to neutralize malicious scripts. 2. Employ Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts in browsers. 3. Conduct a thorough code review of the registration and login modules to identify and remediate any other potential injection points. 4. Implement multi-factor authentication (MFA) to reduce the impact of session hijacking if an XSS attack is successful. 5. Monitor web application logs for unusual input patterns or repeated attempts to inject scripts. 6. Educate users, particularly administrators, about the risks of clicking on suspicious links or executing unexpected actions prompted by the application. 7. If possible, isolate the user management system from critical backend systems to limit lateral movement in case of compromise. 8. Regularly back up user data and configurations to enable recovery in case of an attack. 9. Engage with the vendor or community maintaining the system to obtain or request security patches or updates. 10. Consider deploying web application firewalls (WAFs) with rules specifically designed to detect and block XSS payloads targeting the affected parameters.
