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. However, denial-of-service (DoS) attacks remain a concern.

Klassifikation & Betroffenheit:

CWE-120 Dahua IPC Affected products include certain models from the IPC-1XXX, IPC-2XXX, IPC-WX, and IPC-ECXX series, and limited to versions which build time before April 16, 2025.SD Affected products include certain models from the SD3A, SD2A, SD3D, SDT2A, and SD2C series, and limited to versions which build time before April 16, 2025.

Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') 🎯 High

The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer.

🛡️ Empfohlene Mitigation: Use a language that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid. For example, many languages that perform their own memory management, such as Java and Perl, are not subject to buffer overflows. Other languages, such as Ada and C#, typically provide overflow prot…
