Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

SeaCMS version 12.9 contains a remote code execution vulnerability in the /augap/adminip.php component. The flaw is identified as CVE-2023-46987 and is categorized under CWE-94, with a CVSS 3.1 score of 8.8 indicating network attack vector, low complexity, low privileges required, and no user interaction needed for high impact on confidentiality, integrity, and availability.

An attacker able to reach the affected component with low-level credentials can supply input that leads to arbitrary code execution on the server, resulting in full compromise of the SeaCMS installation and underlying host.

The listed references consist of the vendor site and a technical write-up but contain no details on patches, configuration changes, or other mitigations.

The associated EPSS score remains flat at 0.0575 with no material rise from its recorded peak.

Likely Mitigating Controls AI

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.

PR.PS-06 mostly match
blocks

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
blocks

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.
