Last modified

CVE-2025-31701 is a high-severity vulnerability rated 8.1/10 on the CVSS scale. A vulnerability has been found in Dahua products. Attackers could exploit a buffer overflow vulnerability by sending specially crafted malicious packets, potentially causing service disruption (e.g., crashes) or remote code execution (RCE). Some devices may have deployed protection mechanisms such as Address Space Layout Randomization (ASLR), which reduces the likelihood of successful RCE exploitation. EPSS estimates a 0.80% chance of exploitation in the next 30 days.

Description

A vulnerability has been found in Dahua products. Attackers could exploit a buffer overflow vulnerability by sending specially crafted malicious packets, potentially causing service disruption (e.g., crashes) or remote code execution (RCE).
