A heap-based buffer overflow vulnerability in the WS-Addressing Action transformation function in the Sofia IPC daemon in Xiongmai IP Camera XM530… (CVE-2026-79393)
A heap-based buffer overflow vulnerability exists in the WS-Addressing Action transformation function of the Sofia IPC daemon in Xiongmai IP Camera XM530 firmware HMT.CM2005-v220608.1837 and earlier. This vulnerability can be triggered remotely by unauthenticated attackers sending a crafted SOAP request with a wsa5:Action string longer than 128 bytes. Exploitation may cause denial of service or potentially allow arbitrary code execution.
AI Analysis
Technical Summary
CVE-2026-79393 describes a heap-based buffer overflow in the WS-Addressing Action transformation function within the Sofia IPC daemon of Xiongmai IP Camera XM530 devices running firmware version HMT.CM2005-v220608.1837 and earlier. The flaw is triggered by a crafted SOAP request containing a wsa5:Action string exceeding 128 bytes, which can lead to a crash or potentially arbitrary code execution by remote unauthenticated attackers.
Potential Impact
The vulnerability allows remote unauthenticated attackers to cause denial of service by crashing the IPC daemon or potentially execute arbitrary code, which could compromise the affected device. The CVSS score of 7.5 (high) reflects the network attack vector with no privileges or user interaction required and impact on availability.
Mitigation Recommendations
No patch or official fix information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, consider restricting network access to the affected device to trusted sources to reduce exposure.
