Alert meAnalysisAI
KiTTY versions 0.76.1.13 and before is vulnerable to a stack-based buffer overflow via the username, occurs due to insufficient bounds checking and input sanitization (at line 2600). Rated high severity (CVSS 7.8), this vulnerability is low attack complexity. Public exploit code available and no vendor patch available.
RemediationAI
No vendor patch is available at time of analysis. Monitor vendor advisories for updates. Validate write boundaries, use memory-safe languages, enable compiler protections (ASLR, stack canaries).

Technical ContextAI · show details
This vulnerability is classified as Out-of-bounds Write (CWE-787), which allows attackers to write data beyond allocated buffer boundaries leading to code execution or crashes. KiTTY versions 0.76.1.13 and before is vulnerable to a stack-based buffer overflow via the username, occurs due to insufficient bounds checking and input sanitization (at line 2600). This allows an attacker to overwrite adjacent memory, which leads to arbitrary code execution. Affected products include: 9Bis Kitty.

Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
