CVE-2025-5031Public exploitNetwork attack vector

Processing failure via unchecked wxapkg metadata

Published May 21, 2025 · Updated May 21, 2025

Resource exhaustion in Ackites KillWxapkg 2.4.0 through 2.4.1 allows remote attackers to interrupt processing via a crafted wxapkg file. UnpackWxapkg trusts attacker-controlled file-count, offset, and size metadata, allowing many entries to reference the same small payload while writing repeated outputs without resource limits. A user must process the file; successful exploitation consumes excessive memory or disk space and can stop the tool from completing its work.
