CVE-2025-15546: CWE-362 Race Condition (Concurrent Execution using Shared Resource with Improper Synchronization) in Iptanus File Upload
The Iptanus File Upload WordPress plugin before 5.1.7 does not implement proper file handling when the duplicatepolicy setting is configured to "maintain both." Due to a Time-of-Check to Time-of-Use (TOCTOU) race condition between the file existence check and the actual file write operation, an authenticated attacker can overwrite files uploaded by other users.
AI Analysis
Technical Summary
CVE-2025-15546 is a race condition vulnerability (CWE-362) in the Iptanus File Upload WordPress plugin versions prior to 5.1.7. When the plugin's duplicatepolicy setting is configured to "maintain both," it fails to properly synchronize file handling operations, leading to a time-of-check to time-of-use (TOCTOU) race condition. This flaw allows an authenticated attacker to overwrite files uploaded by other users by exploiting the gap between the file existence check and the actual file write operation.
Potential Impact
An authenticated attacker can overwrite files uploaded by other users, potentially leading to data integrity issues or unauthorized modification of uploaded content. The vulnerability does not impact confidentiality but affects integrity and availability to a limited extent. The attack requires low privileges and user interaction, and the complexity is high due to the race condition nature.
Mitigation Recommendations
No official fix or patch is currently confirmed for this vulnerability. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, administrators should consider disabling or restricting the use of the duplicatepolicy setting "maintain both" if possible, or limit authenticated user permissions to reduce risk.
