Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') (CWE-22)
This vulnerability allows remote attackers to delete arbitrary directories on affected installations of Logsign Unified SecOps Platform. Authentication is required to exploit this vulnerability. The specific flaw exists within the HTTP API service, which listens on TCP port 443 by default. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to delete directories in the context of root.
The vulnerability has a high impact on availability, as it allows authenticated attackers to delete arbitrary directories on the affected system. This could lead to severe disruption of services, data loss, or system instability. The integrity impact is also high, as the attacker can modify the system structure by deleting directories. There is no direct impact on confidentiality. The attack vector is network-based, with low attack complexity and no user interaction required, making it relatively easy to exploit once an attacker has low-level privileges. The vulnerability has a CVSS v3.1 base score of 8.1 (High), with a vector string of CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:H.
One proof-of-concept exploit is available on zerodayinitiative.com. There is no evidence of proof of exploitation at the moment.
Logsign has issued an update to correct this vulnerability. The patch is available in version 6.4.23 of the Logsign Unified SecOps Platform. More details can be found in the release notes at: https://support.logsign.net/hc/en-us/articles/20617133769362-06-08-2024-Version-6-4-23-Release-Notes
1. Update the Logsign Unified SecOps Platform to version 6.4.23 or later as soon as possible. 2. Implement strong authentication mechanisms and regularly review and update user access privileges to minimize the risk of exploitation. 3. Monitor system logs for any suspicious activities related to directory deletions or unauthorized access attempts. 4. Implement network segmentation to restrict access to the HTTP API service (TCP port 443) only to necessary users and systems. 5. Regularly backup critical data and configurations to mitigate potential data loss in case of successful exploitation.
