CVE-2023-28343
Published: April 11, 2026
Official Description
OS command injection affects Altenergy Power Control Software C1.2.5 via shell metacharacters in the index.php/management/set_timezone timezone parameter, because of set_timezone in models/management_model.php.
Risk Analysis
This OS command injection vulnerability in Altenergy Power Control Software C1.2.5 allows an attacker to execute arbitrary operating system commands. This is due to improper handling of shell metacharacters in the timezone parameter. The confirmed exploitation in the wild makes this a critical vulnerability.
This vulnerability is actively being exploited in the wild. An attacker can remotely execute commands by injecting shell metacharacters into the timezone parameter via the index.php/management/set_timezone endpoint.
Upgrade Altenergy Power Control Software to a version beyond C1.2.5. Implement strict input validation and sanitization for all user-supplied data, especially parameters that interact with system commands.
Technical Analysis
CVE-2023-28343 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
CISA has added CVE-2023-28343 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
