CVE-2024-9257 is an improper input validation vulnerability classified under CWE-20, affecting Logsign Unified SecOps Platform version 6.4.24. The vulnerability exists in the delete_gsuite_key_file endpoint, where the application fails to properly validate user-supplied filenames before performing file deletion operations. This flaw allows an authenticated remote attacker to specify arbitrary filenames, potentially deleting critical files within sensitive directories on the affected system. The vulnerability does not require user interaction but does require the attacker to have valid credentials with access to the vulnerable endpoint. The CVSS v3.0 score is 4.3 (medium), reflecting that the attack vector is network-based with low attack complexity and privileges required, but no impact on confidentiality or availability. The vulnerability could lead to integrity loss by deleting important files, which might disrupt the platform’s operation or compromise system stability. No public exploits have been reported yet, but the vulnerability was reserved and published by the Zero Day Initiative (ZDI) under CAN-25265. Since the affected product is a security operations platform, exploitation could undermine incident response capabilities, making timely remediation critical.

The primary impact of CVE-2024-9257 is the loss of integrity due to arbitrary file deletion on systems running Logsign Unified SecOps Platform 6.4.24. Deletion of critical files could disrupt the platform’s functionality, potentially impairing security monitoring and incident response activities. This could lead to delayed detection of other attacks or loss of forensic data. Although confidentiality and availability are not directly affected, the operational impact on security teams could be significant, especially in environments relying heavily on this platform for unified security operations. Organizations with high dependency on Logsign for security orchestration and monitoring may face increased risk of operational disruption. The requirement for authentication limits exploitation to insiders or compromised accounts, but the low complexity of the attack increases risk if credentials are exposed. No known exploits in the wild reduce immediate risk, but the vulnerability should be addressed promptly to prevent future exploitation.

Organizations should implement the following specific mitigations: 1) Apply vendor patches or updates as soon as they become available to fix the input validation flaw. 2) Restrict access to the delete_gsuite_key_file endpoint to only trusted and necessary users, employing the principle of least privilege. 3) Implement strong authentication mechanisms, including multi-factor authentication, to reduce risk of credential compromise. 4) Monitor and audit file deletion operations and access logs related to the vulnerable endpoint for suspicious activity. 5) Employ application-layer input validation controls or web application firewalls (WAFs) to detect and block malicious filename inputs targeting this endpoint. 6) Conduct regular security reviews of user permissions and endpoint exposure within the Logsign platform. 7) Consider network segmentation to isolate the SecOps platform from less trusted network zones. These measures go beyond generic advice by focusing on access control, monitoring, and layered defenses specific to the vulnerability context.
