CVE-2026-0791 Details
Description
ALGO 8180 IP Audio Alerter SIP INVITE Replaces Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of ALGO 8180 IP Audio Alerter devices. Authentication is not required to exploit this vulnerability. The specific flaw exists within the handling of the Replaces header of SIP INVITE requests. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the device. Was ZDI-CAN-28300.
A stack-based buffer overflow vulnerability has been identified in the ALGO 8180 IP Audio Alerter, allowing remote code execution. This issue arises from improper validation of the Replaces header in SIP INVITE requests, which enables attackers to exploit the vulnerability without authentication. The flaw exists because user-supplied data can be copied to a fixed-length buffer on the stack without adequate length checks, creating an opportunity for arbitrary code execution in the context of the affected device.
The recommended mitigation strategy is to restrict interaction with the affected product.
