Description

CVE-2026-76689 is a high-severity vulnerability in the configuration processing logic of an unspecified component. It allows an authenticated remote attacker with administrative privileges to trigger a stack-based buffer overflow by submitting specially crafted configuration data. This can lead to remote code execution with root privileges or cause a denial of service through a system crash.

Technical Analysis

This vulnerability arises from improper handling of malformed input in the configuration processing logic of the affected component. An attacker who is authenticated and has administrative privileges can exploit this flaw by providing crafted configuration data, resulting in a stack-based buffer overflow. The overflow may enable remote code execution with root privileges or cause a denial of service by crashing the system. The CVSS 3.1 base score is 7.2, reflecting high impact on confidentiality, integrity, and availability.

Potential Impact

Successful exploitation can lead to remote code execution with root privileges, allowing full system compromise. Alternatively, it can cause a denial of service by crashing the affected system. The attacker must be authenticated with administrative privileges to exploit this vulnerability.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict administrative access and validate configuration inputs carefully to mitigate risk.
