Cleartext Transmission of Sensitive Information (CWE-319) in a component used in the Gallagher Hanwha VMS and Gallagher NxWitness VMS integrations allows unprivileged users with local network access to view live video streams. 

 

This issue affects all versions of Gallagher NxWitness VMS integration prior to 9.10.017 and Gallagher Hanwha VMS integration prior to 9.10.025.

CVE-2026-20801 is a vulnerability categorized under CWE-319, which involves the cleartext transmission of sensitive information. Specifically, this flaw exists in components used by Gallagher NxWitness VMS and Hanwha VMS integrations, which are video management systems widely used for security surveillance. The vulnerability allows an attacker with local network access but no privileges or user interaction to intercept live video streams transmitted without encryption. This exposure arises because sensitive data, including live video feeds, are sent over the network in plaintext, enabling eavesdropping and unauthorized viewing. The affected versions include all releases prior to 9.10.017 for Gallagher NxWitness VMS integration and prior to 9.10.025 for Gallagher Hanwha VMS integration. The CVSS v3.1 base score is 5.6 (medium), reflecting network attack vector, high attack complexity, no privileges required, no user interaction, and limited confidentiality, integrity, and availability impacts. No known exploits have been reported in the wild, and no official patches have been linked yet, though vendors typically address such issues in subsequent updates. The vulnerability's root cause is the lack of encryption or secure transmission protocols for sensitive video data, violating best practices for protecting surveillance streams. This flaw could be exploited in environments where attackers have access to the same local network segment, such as corporate LANs, wireless networks, or poorly segmented networks, allowing them to capture and view live video streams without authorization.
