CVE-2025-6829 is a critical SQL Injection vulnerability identified in the aaluoxiang oa_system, specifically affecting the function outAddress within the External Address Book Handler component. The vulnerability arises from improper sanitization or validation of user-supplied input, allowing an attacker to inject malicious SQL queries. This flaw can be exploited remotely without requiring user interaction or elevated privileges, as indicated by the CVSS vector (AV:N/AC:L/PR:L/UI:N). The oa_system product does not implement versioning, complicating the determination of affected and unaffected releases. The vulnerability's CVSS score is 5.3 (medium severity), reflecting limited impact on confidentiality, integrity, and availability, and the requirement of some privileges (PR:L). Exploitation could lead to unauthorized data access, modification, or deletion within the database managed by the External Address Book Handler, potentially exposing sensitive contact information or disrupting system operations. No known public exploits or patches are currently available, increasing the risk of exploitation if attackers discover or develop exploit code. The absence of versioning and patch information necessitates careful inspection of deployed oa_system instances to assess exposure.

For European organizations using the aaluoxiang oa_system, this vulnerability poses a moderate risk. The SQL Injection could compromise sensitive internal contact data stored in the External Address Book, leading to data breaches or unauthorized data manipulation. This may affect confidentiality and integrity of organizational information. Additionally, exploitation could disrupt business processes relying on the address book, impacting availability. Given the remote attack vector and lack of user interaction, attackers could automate exploitation attempts, increasing risk. Organizations in sectors with strict data protection regulations (e.g., GDPR) face potential compliance violations and reputational damage if breaches occur. The medium CVSS score suggests limited but non-negligible impact, especially if the oa_system is integrated with other critical systems or contains sensitive personal or corporate data.

1. Conduct a thorough audit of all deployed instances of aaluoxiang oa_system to identify affected versions, despite the lack of formal versioning. 2. Implement input validation and parameterized queries or prepared statements in the outAddress function to prevent SQL Injection. 3. Employ Web Application Firewalls (WAFs) with custom rules to detect and block SQL Injection attempts targeting the External Address Book Handler. 4. Monitor logs for unusual database query patterns or errors indicative of injection attempts. 5. Restrict database user privileges associated with the oa_system to the minimum necessary to limit potential damage. 6. Engage with the vendor or community to obtain patches or updates; if unavailable, consider code review and custom patching. 7. Isolate the oa_system environment where possible to reduce lateral movement risk. 8. Educate internal security teams about this vulnerability to enhance detection and response capabilities.
