Operationally, exploitation aligns with the MITRE ATT&CK technique NTDS (T1003.003); ranked in the top 3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis AI-assisted summary

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

GL.iNET MT3000 firmware version 4.1.0 Release 2 contains an OS command injection vulnerability, tracked as CVE-2023-29778 with CWE-78, in the component located at /usr/lib/oui-httpd/rpc/logread. The flaw received a CVSS 3.1 score of 9.8, reflecting network-accessible attack vectors that require no authentication or user interaction and result in complete loss of confidentiality, integrity, and availability.

An unauthenticated remote attacker can supply crafted input to the affected RPC endpoint and execute arbitrary operating-system commands on the device. Successful exploitation grants the attacker full control over the router, enabling actions such as traffic interception, persistence installation, or lateral movement within attached networks.

Public references point to GL.iNET product information and a detailed technical write-up that demonstrates the injection via the nginx log retrieval function, though no official patch or mitigation guidance is included in the available sources. The associated EPSS score rose from a low baseline to a peak of 0.2816 before receding to its current value of 0.1224, indicating a period of increased exploitation interest after disclosure.

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.

SC-27 Platform-independent Applications
addresses: CWE-78

Platform-independent apps typically execute inside a managed runtime or sandbox that restricts direct OS command execution, reducing the ability to exploit OS command injection.

SI-10 Information Input Validation
addresses: CWE-78

Validates inputs to block special elements that would alter OS command execution.

PR.PS-06 mostly match
blocks

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.

PR.PS-02 partial match
blocks

Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
