Security readout for executives and security teams
Plain-English summary
This flaw could let a highly privileged user on Avaya Aura Utility Services run specially crafted scripts with elevated privileges. It is not described as remotely exploitable by an unauthenticated attacker, but compromise of trusted accounts could become more damaging.
Executive priority
Treat as high priority where Avaya Aura Utility Services supports critical communications. Urgency is lower than internet-facing unauthenticated flaws, but privileged access abuse could materially increase attacker control after account compromise.
Technical view
CVE-2021-25650 is a CWE-250 privilege escalation issue in Avaya Aura Utility Services. The source says all 7.x versions are affected, with CVSS 3.1 score 7.7 and vector AV:N/AC:H/PR:H/UI:N/S:C/C:H/I:H/A:N.
Likely exposure
Exposure is limited to organizations running Avaya Aura Utility Services 7.x. The bundle specifically lists version 7.0.0.0 and also states all 7.x versions are affected, so version scoping should be checked against Avaya guidance.
Exploitation context
The bundle does not show CISA KEV listing or active exploitation evidence. Exploitation requires high privileges and high attack complexity, but successful abuse could allow privileged script execution and impact confidentiality and integrity.
Researcher notes
The source bundle contains limited remediation detail. Note the description emphasizes a local user, while the CVSS vector lists network attack vector; validate interpretation against Avaya’s advisory before modeling attack paths.
Mitigation direction
- Check Avaya advisory 101072728 for official fixed versions or mitigation guidance.
- Inventory Avaya Aura Utility Services deployments and identify all 7.x instances.
- Prioritize upgrades or vendor-recommended remediation for exposed or business-critical systems.
- Restrict administrative and local user access to Utility Services hosts.
- Monitor privileged script execution and administrative account activity.
Validation and detection
- Confirm deployed Avaya Aura Utility Services versions against the affected 7.x range.
- Review Avaya advisory details before declaring systems remediated.
- Verify access controls limit high-privilege users on affected hosts.
- Check logs for unusual privileged script execution or administrative activity.
- Document exceptions where vendor remediation cannot yet be applied.

Execution with Unnecessary Privileges
Execution with Unnecessary Privileges represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
