CVE-2024-25003

CWE-787Published: February 9, 2024· Updated: Jun 17, 2026

7.8

CVSS v3.1

Official Description

KiTTY versions 0.76.1.13 and before is vulnerable to a stack-based buffer overflow via the hostname, occurs due to insufficient bounds checking and input sanitization. This allows an attacker to overwrite adjacent memory, which leads to arbitrary code execution.

Technical Analysis

CVE-2024-25003 requires local access, meaning attackers must already have a foothold on the target system.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.

A proof-of-concept (PoC) exploit exists for CVE-2024-25003. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.

From a weakness classification perspective (CWE-787): Out-of-bounds write vulnerabilities can lead to data corruption, crashes, or arbitrary code execution.
