Overview<\/strong><\/p>\n

The vulnerability, designated as CVE-2025-45994, poses a significant threat to the security of Aranda PassRecovery v1.0, a widely-used software solution. This flaw enables attackers to enumerate valid user accounts in Active Directory via a specially crafted POST request, potentially leading to system compromise or data leakage. Given the high severity score of 7.5, it is crucial for organizations using this software to implement mitigation measures promptly.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-45994
\nSeverity: High (7.5 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise, data leakage<\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

Aranda PassRecovery | v1.0<\/p>\n

How the Exploit Works<\/strong><\/p>\n

This exploit works by sending a crafted POST request to the endpoint \/user\/existdirectory\/1. The issue lies in the handling of these requests by the Aranda PassRecovery v1.0 software. An attacker can manipulate the request to enumerate valid user accounts in the Active Directory, thus gaining unauthorized access to sensitive information.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Below is a conceptual example of how the vulnerability might be exploited in a HTTP request:<\/p>\n

POST \/user\/existdirectory\/1 HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"username\": \"admin\" }<\/code><\/pre>\n
In this example, the attacker is attempting to enumerate whether the “admin” username exists in the system.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
Immediate mitigation measures for this vulnerability include applying the vendor patch, if available. As a temporary mitigation, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can help detect and prevent exploitation attempts. Long-term, it is recommended to always keep your software up to date with the latest patches and security updates.<\/p>\n","protected":false},"excerpt":{"rendered":"
