CVE-2024-25655 identifies a security vulnerability in the AVSystem Unified Management Platform (UMP) version 23.07.0.16567~LTS, specifically related to the insecure storage of LDAP passwords within the platform's authentication functionality. The vulnerability arises because LDAP passwords are stored in a manner that allows any user with read access to the application database to decrypt these passwords. This means that if an attacker or malicious insider gains read privileges on the database, they can retrieve plaintext LDAP credentials of users who have successfully authenticated to the web management interface via LDAP. The vulnerability is classified under CWE-922 (Insecure Storage of Credentials). The CVSS v3.1 base score is 6.5, indicating a medium severity level. The attack vector is network-based (AV:N), with low attack complexity (AC:L), requiring privileges (PR:L) but no user interaction (UI:N). The impact is primarily on confidentiality (C:H), with no impact on integrity or availability. No patches or exploits are currently publicly available. This vulnerability could be exploited by insiders or attackers who have gained limited access to the database, enabling them to escalate privileges or move laterally by leveraging decrypted LDAP credentials. The lack of secure credential storage violates best practices for protecting sensitive authentication data and increases the risk of credential compromise.

The primary impact of CVE-2024-25655 is the compromise of confidentiality of LDAP credentials stored within the AVSystem UMP database. If an attacker or unauthorized insider obtains read access to the application database, they can decrypt LDAP passwords, potentially allowing them to impersonate legitimate users or escalate privileges within the network. This can lead to unauthorized access to sensitive management interfaces and systems, increasing the risk of further exploitation, data breaches, or disruption of managed devices. Organizations relying on AVSystem UMP for device management and authentication may face increased risk of insider threats or external attackers leveraging stolen credentials for lateral movement. The vulnerability does not directly affect system integrity or availability but can indirectly facilitate attacks that do. Since LDAP is commonly used for centralized authentication in enterprise environments, exposure of these credentials can have broad security implications, especially in environments with high-value targets or critical infrastructure. The absence of known exploits reduces immediate risk, but the vulnerability remains a significant concern for organizations with inadequate database access controls.

To mitigate CVE-2024-25655, organizations should implement the following specific measures: 1) Restrict and tightly control read access to the AVSystem UMP application database, ensuring only trusted administrators have such privileges. 2) Audit and monitor database access logs for unusual or unauthorized read operations to detect potential exploitation attempts early. 3) If possible, upgrade to a patched version of AVSystem UMP once available or apply vendor-recommended fixes that address secure storage of LDAP credentials. 4) Implement encryption-at-rest and secure credential storage mechanisms within the application or database to prevent plaintext password exposure. 5) Enforce strong LDAP credential policies, including frequent password rotation and multi-factor authentication, to reduce the impact of credential compromise. 6) Segment the network and isolate management platforms to limit exposure if credentials are leaked. 7) Conduct regular security assessments and penetration testing focused on database access controls and credential management. These steps go beyond generic advice by focusing on access control, monitoring, and secure storage practices tailored to the specific vulnerability context.
