Vulnerability details

SeaCMS 13.0 has a remote code execution vulnerability. The reason for this vulnerability is that although admin_files.php imposes restrictions on edited files, attackers can still bypass these restrictions and write code, allowing authenticated attackers to exploit the vulnerability to execute…

MITRE ATT&CK Enterprise TechniquesAI

T1505.003 Web Shell Persistence
Adversaries may backdoor web servers with web shells to establish persistent access to systems.
T1190 Exploit Public-Facing Application Initial Access
Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.
T1221 Template Injection Stealth
Adversaries may create or modify references in user document templates to conceal malicious code or force authentication attempts.
Why these techniques?

Vulnerability enables authenticated RCE by bypassing file edit restrictions via path traversal to inject PHP webshell code (e.g., eval) into template files like admin_files.htm, exploiting public-facing web app and template injection for web shell deployment and command execution.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-94

Makes persistent code injection into loaded programs impossible when the executable image itself resides on hardware-protected read-only media.

addresses: CWE-94

Dynamically generated code can be produced and executed inside the isolated chamber, preventing host compromise from code-injection payloads.

addresses: CWE-94

Validates inputs used in dynamic code generation to block injected directives.

addresses: CWE-94

Directly prevents execution of attacker-supplied code written into data memory regions.
