Lifecycle Timeline
6DescriptionCVE.org
TuneClone 2.20 contains a structured exception handler (SEH) buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying a malicious license code string. Attackers can craft a payload with a controlled buffer, NSEH jump instruction, and SEH handler address pointing to a ROP gadget, then paste it into the license code field to trigger code execution and establish a bind shell.
AnalysisAI
TuneClone 2.20 contains a structured exception handler (SEH) buffer overflow vulnerability that allows local attackers to execute arbitrary code by supplying a malicious license code string.
Technical ContextAI
An out-of-bounds memory access occurs when code reads from or writes to memory locations outside the intended buffer boundaries. This vulnerability is classified as Out-of-bounds Write (CWE-787).
RemediationAI
Implement proper bounds checking on all array and buffer accesses. Use memory-safe languages or static analysis tools to detect OOB issues.
