Summary

CVE-2020-36925 is a critical-severity Insufficient Entropy (CWE-331) vulnerability in Ibmcloud (inferred from references). Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 30.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

The strongest mitigations our analysis identified are NIST 800-53 AC-17 (Remote Access) and IA-5 (Authenticator Management).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

IA-5 Authenticator Management good match

prevent

IA-5 requires authenticators, including session IDs, to have sufficient strength of mechanism and complexity to resist brute-force guessing attacks.

SC-23 Session Authenticity good match

preventdetect

SC-23 mandates mechanisms to protect the authenticity of communications sessions, directly countering session hijacking via weak session IDs.

AC-17 Remote Access good match

prevent

AC-17 requires protections for remote access sessions against hijacking, applicable to the web client allowing unauthorized remote access to camera streams.

MITRE ATT&CK Enterprise TechniquesAI

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.

Why these techniques?

The vulnerability enables remote unauthenticated attackers to brute-force weak session IDs in a public-facing web application (Arteco Web Client DVR/NVR), hijacking sessions to bypass authentication and access live camera streams, directly facilitating T1190: Exploit Public-Facing Application.

NVD Description

Arteco Web Client DVR/NVR contains a session hijacking vulnerability with insufficient session ID complexity that allows remote attackers to bypass authentication. Attackers can brute force session IDs within a specific numeric range to obtain valid sessions and access live camera…

streams without authorization.

Deeper analysisAI

CVE-2020-36925 is a session hijacking vulnerability in the Arteco Web Client DVR/NVR software, stemming from insufficient session ID complexity (CWE-331). The flaw enables remote attackers to brute force session IDs within a specific numeric range, bypassing authentication mechanisms entirely. Rated at CVSS 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), it poses a critical risk due to its high confidentiality, integrity, and availability impacts.

Any remote attacker can exploit this vulnerability without prerequisites like user interaction or privileges, simply by guessing valid session IDs through brute force. Successful exploitation grants unauthorized access to live camera streams, allowing attackers to view sensitive video feeds from the DVR/NVR system.
