Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly mitigates the CVE by requiring timely patching of the arbitrary file upload flaw in admin/plugin.php that enables code execution via crafted ZIP files.
Enforces information input validation at the plugin upload interface to detect and reject crafted ZIP files containing arbitrary code.
Restricts file types, sizes, and other input parameters at upload points to block unrestricted uploads of dangerous ZIP files.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Arbitrary file upload in public-facing admin component directly enables remote exploitation (T1190) and malicious file ingress for code execution (T1105).
NVD Description
An arbitrary file upload vulnerability in the component admin\plugin.php of Emlog Pro v2.5.3 allows attackers to execute arbitrary code via uploading a crafted Zip file.
