Unauthenticated Arbitrary File Deletion in Participants Database <= 2.7.8.4 versions.
AI Analysis
Technical Summary
This vulnerability (CWE-22) in Participants Database versions <= 2.7.8.4 allows unauthenticated attackers to perform arbitrary file deletion via path traversal. The flaw arises from insufficient validation of file paths, enabling attackers to escape restricted directories and delete files outside the intended scope. The CVSS 3.1 base score is 7.4, reflecting network attack vector, low attack complexity, no privileges required, user interaction required, scope changed, no confidentiality or integrity impact, but high availability impact.
Potential Impact
An unauthenticated attacker can delete arbitrary files on the system hosting the Participants Database, potentially causing denial of service or disruption of service availability. There is no direct impact on confidentiality or integrity according to the CVSS vector.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround is currently documented. Until a patch is available, restrict access to the application and monitor for suspicious activity related to file operations.
