Description

CVE-2024-34521 is a directory traversal vulnerability found in Mavenir SCE Application Provisioning Portal version PORTAL-LBS-R_1_0_24_0. This flaw enables an authenticated administrative user to access sensitive system files with the privileges of the system user running the application. The SOCRadar Vulnerability Risk Score (SVRS) for this CVE is 38.

Key Insights

• Privileged Access: The directory traversal allows an attacker with administrative privileges to bypass intended access restrictions and view system files as if they were the system user. This can lead to the disclosure of sensitive information, including configuration files, credentials, and internal code.
• Internal Threat Focus: The vulnerability is exploitable by administrative users, indicating a potential risk from malicious insiders or compromised administrator accounts.
• Limited Severity per SVRS: While the vulnerability exists, the SVRS score of 38 suggests the risk is not critical. The primary factors contributing to this score likely include the requirement for administrative access and the lack of active exploitation in the wild.
• No public information indicates that there are active exploits of the vulnerability, specific Threat Actors/APT Groups exploiting it, CISA Warnings or being used in the wild.

Mitigation Strategies

1. Input Validation and Sanitization: Implement robust input validation and sanitization techniques in the Mavenir SCE Application Provisioning Portal to prevent directory traversal attacks. This includes carefully validating user-supplied file paths and preventing the use of characters like ".." that allow traversal to parent directories.
2. Least Privilege Principle: Review and enforce the principle of least privilege for administrative users. Restrict their access to only the files and directories necessary for their roles. Regularly audit access controls.
3. Update to a Patched Version: Check the availability of newer versions of Mavenir SCE Application Provisioning Portal. Update to a patched version as soon as it is released by the vendor to remediate the vulnerability.
4. Internal Threat Detection: Implement monitoring and alerting mechanisms to detect suspicious activity by administrative users. This could include monitoring access to sensitive system files or unusual patterns of file access.
