Unauthenticated server crash via overlong upload filename
Published Aug 7, 2026 · Updated Aug 7, 2026
Out-of-bounds write in TeamDavid Webbox through Rollout 524 allows remote attackers to crash the server via an overlong upload filename. The affected upload handlers process an attacker-controlled filename without enforcing the destination buffer length. No authentication is required; observed exploitation terminates the process with STATUS_STACK_BUFFER_OVERRUN, while code execution requires favorable stack state or disclosure of a stack canary.
