Security readout for executives and security teams
Plain-English summary
This vulnerability could let an attacker trick a logged-in Avaya administrator into performing unwanted web administration actions. It affects specific Avaya Aura Communication Manager and Aura Messaging versions. The issue is not listed as known exploited in the provided sources, but it can create business risk where privileged web admin sessions are reachable and used regularly.
Executive priority
Treat this as a moderate-priority remediation item for Avaya voice and messaging environments. Prioritize systems with active administrator use, broad network reachability, or high operational dependence on Avaya services.
Technical view
CVE-2020-7029 is a CSRF flaw in the System Management Interface Web component. An unauthenticated remote attacker could cause actions to run with the privileges of an authenticated user. CVSS 3.1 is 6.4, with network attack vector, high complexity, required user interaction, and high integrity impact.
Likely exposure
Exposure is likely limited to organizations running the affected Avaya Aura versions and using the SMI web administration interface. The affected Communication Manager versions are 7.0.x, 7.1.x before 7.1.3.5, and 8.0.x. Affected Messaging versions are 7.0.x, 7.1, and 7.1 SP1.
Exploitation context
The provided sources do not show active exploitation or CISA KEV listing. Exploitation requires user interaction and an authenticated privileged user context, which lowers likelihood but keeps impact meaningful because successful abuse can perform administration actions.
Researcher notes
The source bundle establishes affected versions, CWE-352, CVSS 6.4, and the CSRF impact model. It does not provide exploit details, observed exploitation, or named fixed versions beyond Communication Manager 7.1.x prior to 7.1.3.5 being affected.
Mitigation direction
- Identify affected Avaya Aura Communication Manager and Messaging deployments.
- Review the Avaya advisory for vendor-approved updates or remediation guidance.
- Restrict SMI access to trusted administrative networks where feasible.
- Reduce administrator exposure to untrusted web content during active sessions.
- Review privileged web administration procedures for CSRF risk.
Validation and detection
- Confirm installed Communication Manager and Messaging versions against the affected ranges.
- Verify whether the System Management Interface Web component is enabled and reachable.
- Check whether administrative access is limited to trusted networks or VPN paths.
- Review web administration logs for unexpected privileged changes.
- Document vendor advisory status and planned remediation owner.
