Title
Unauthenticated file read in Mikrotik RouterOS
Summary
RouterOS WebFig contains an unauthenticated file-read vulnerability in the /jsproxy path where a newly allocated session retains a stale uninitialized principal pointer used for file authorization. An unauthenticated attacker can prepare the allocator so that the file-serving path dereferences this pointer with sufficient rights, then supply parent-directory components in an encrypted URI to escape the WebFig file namespace and disclose root-owned files, including configuration stores containing credentials.This issue was fixed in versions: 6.49.21 (Long-term), 7.23.4 (Long-term) and 7.24.2 (Stable)
CWE
  • CWE-824 - Access of uninitialized pointer
  • CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
