Summary

JetBackup plugin for WordPress before 3.1.24.10 contains a symlink-based arbitrary file write flaw, tracked as CWE-59 (link following). An authenticated WordPress administrator can craft a backup archive with a symbolic link that archive extraction follows during import and restore, writing attacker-controlled content outside the intended restore destination. Depending on the writable destination and server configuration, this could lead to server-side code execution.

Description from the CNA

JetBackup plugin for WordPress before 3.1.24.10 contains a symlink-based arbitrary file write vulnerability that allows an authenticated WordPress administrator to write attacker-controlled file contents outside the intended restore destination during backup import and restore. Attackers can craft a backup archive containing a symbolic link that archive extraction follows without validating targets or enforcing destination containment, potentially leading to server-side code execution depending on the writable destination and server configuration.
