Horizon Alert
Summary of the vulnerability and why it matters
This advisory details a security vulnerability in WWBN AVideo software that could allow an administrator to inject malicious code, impacting other administrators who manage user groups. The primary concern is confirming if this specific type of administrative access and user interaction exists within your environment.
- Malicious code can be hidden in user group names.
- Affects administrators managing other administrators.
- Confirm relevance and potential exposure within your system.
Attack Path
How an attacker could exploit the issue
An attacker with administrative privileges can exploit this vulnerability by manipulating user group names to inject malicious code. This code will execute when another administrator accesses the user management interface, potentially leading to further compromise.
- Requires administrator access to modify group names.
- Triggered when another administrator views user groups.
- Risk of code execution in administrative browsers.
Live Threat
Current exploitation, exposure, and threat context
When supported by the advisory, administrators with `canAdminUserGroups` permission could inject malicious code into group names. This code may execute in the browser when other administrators access the user manager interface.
- Administrator-level user group data.
- Injecting malicious code into group names.
- Arbitrary code execution in administrator browsers.
Operational Fix
Recommended remediation, mitigation, and detection steps
The application owner is responsible for addressing this vulnerability, as it affects a specific feature within the AVideo application. The first practical step is to confirm the existence and reachability of AVideo instances within your environment, identify the accountable administrator, and then coordinate remediation efforts, possibly during a scheduled maintenance window.
- Application owner to address.
- Verify AVideo instance reachability.
- Plan remediation by risk.
