CVE-2025-5243
Published: 24 July 2025
Summary
CVE-2025-5243 is a critical-severity OS Command Injection (CWE-78) vulnerability in Gov (inferred from references). Its CVSS base score is 10.0 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 14.8% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-2 (Flaw Remediation).
Deeper analysis
CVE-2025-5243 is a critical-severity vulnerability combining unrestricted upload of files with dangerous types and OS command injection in the SMG Software Information Portal. The flaw, tracked under CWE-434 and CWE-78, permits code injection, web shell deployment, and arbitrary code inclusion. It affects all versions of the Information Portal prior to the 13.06.2025 release and carries a CVSS 3.1 score of 10.0 reflecting network-accessible exploitation without authentication or user interaction.
Unauthenticated remote attackers can upload malicious files and execute operating-system commands on the server, resulting in full compromise of the affected web application and underlying host. The changed scope in the CVSS vector indicates that successful exploitation can impact resources beyond the vulnerable component itself.
Turkish government advisories published by USOM and the National Cyber Security Centre reference the issue under identifier TR-25-0174 and direct administrators to apply the vendor-supplied update that removes the affected versions. The associated EPSS score remains low and unchanged at 0.0232 with no observed upward trajectory after disclosure.
