When a specially crafted HTTP request is sent with an oversized Authorization header, the application fails to properly validate the input length before copying it into a fixed-size buffer, resulting in memory corruption and potential remote code execution. Exploitation requires network access and does not require prior authentication.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"twilight","depthScore":15,"depthScoreParts":{"impact":2.8,"likelihood":0.3,"exploitation":12,"ransomware":0},"changes":[]}
