CVE-2026-44887: CWE-94: Improper Control of Generation of Code ('Code Injection') in leiweibau Pi.Alert
CVE-2026-44887 is a critical remote code execution vulnerability in leiweibau Pi. Alert versions prior to 2026-05-07. The web-based configuration editor allows unauthenticated attackers to inject arbitrary Python code into the pialert.conf file. Since the background scan daemon executes this configuration file using Python's exec(), the injected code runs with the daemon's privileges. The default configuration disables web protection, enabling unauthenticated exploitation. This vulnerability has a CVSS score of 9.8 and is fixed as of version 2026-05-07.
AI Analysis
Technical Summary
Pi.Alert, a WIFI/LAN intruder detector with web service monitoring, contains a code injection vulnerability (CWE-94) in its web-based configuration editor prior to 2026-05-07. Attackers can inject arbitrary Python code into the pialert.conf file, which is executed by the background scan daemon via Python's exec() function. With web protection disabled by default, no authentication is required to exploit this, resulting in unauthenticated remote code execution. The vulnerability is addressed in the 2026-05-07 release.
Potential Impact
Successful exploitation allows unauthenticated remote attackers to execute arbitrary Python code with the privileges of the Pi.Alert background scan daemon. This can lead to full system compromise, including confidentiality, integrity, and availability impacts. The CVSS 3.1 base score is 9.8, indicating critical severity with network attack vector, no required privileges or user interaction, and high impact on confidentiality, integrity, and availability.
Mitigation Recommendations
A fix for this vulnerability is included in Pi.Alert version 2026-05-07. Users should upgrade to this version or later to remediate the issue. Until upgraded, enabling web protection to require authentication can mitigate exploitation risk. Patch status is not explicitly confirmed beyond the fixed version; users should verify with the vendor for official advisories and apply the update promptly.
