Path traversal in Pandora archive extractor allows arbitrary file writes outside the extraction directory in pandora analysis
Pandora contains a path traversal vulnerability in its archive extraction worker. When processing a specially crafted archive or disk image, attacker-controlled file paths could be used without ensuring that the resulting destination remained within the intended extraction directory. An attacker able to submit a malicious file for analysis could use path traversal sequences or crafted paths to cause extracted content to be written outside the designated extraction directory, potentially overwriting files accessible to the Pandora worker process. Successful exploitation could result in unauthorized modification of application or system files, denial of service, and potentially further compromise depending on the permissions of the Pandora process and the files that can be overwritten. The vulnerability is addressed by resolving each extraction destination path before writing and verifying that it remains below the expected extraction directory. Extraction attempts resolving outside this directory are rejected and reported as path traversal attempts.
