deserialization-parser-review

To review deserialization vulnerabilities, inspect parsers and loaders for unsafe operations in YAML, JSON, XML, and pickle formats. This involves identifying components processing untrusted input and analyzing them for potential attack vectors like unsafe loaders or template injections.

Common parser attack surfaces include unsafe deserialization loaders, path traversal vectors, template injections, and Server-Side Request Forgery (SSRF). These vulnerabilities occur when components process untrusted YAML, JSON, XML, or pickle data without proper validation.

To assess the exploitability of unsafe pickle loaders, analyze deserialization components to validate if input is attacker-controlled. This risk assessment verifies the exploitability of the attack vector and recommends defensive changes to secure the operation.

Yes, you need security analysis expertise and a comprehensive understanding of deserialization attack patterns to effectively review deserialization components. The process requires this domain knowledge to accurately identify vulnerabilities and validate exploitability in parsers.

Yes, this security review covers XML and YAML template injection vectors alongside path traversal, SSRF, and unsafe loaders. It inspects these parser components to identify potential attack vectors and validate their exploitability within the target codebase.

You should use an automated deserialization review for new codebases to ensure parser operations are secure and do not introduce vulnerabilities. It systematically inspects loaders and validates exploitability, reducing manual overhead when reviewing unfamiliar libraries.
