Arbitrary file read via malicious YAML upload
Published Feb 25, 2021 · Updated Sep 16, 2024
Path traversal in Adobe Commerce UPWARD-php 1.1.4 and earlier allows remote authenticated users to read arbitrary server files. The UPWARD Connector upload path accepts malicious YAML containing file-reading instructions that resolve attacker-controlled paths outside the intended content root. Administrative-console access is required, and the documented consequence is file disclosure rather than file modification or service interruption.
