A flaw was discovered in the AES OAM web interface which could allow non-privileged AES OAM users to perform some operations that are intended to be restricted to privileged OAM users only allowing for an authorization bypass and privilege escalation. The Common Vulnerabilities and Exposures project (cve.mitre.org) has not assigned a CVE to this issue.
Avaya would like to thank Ben Heinkel of Context Information Security Ltd for responsibly reporting this issue.
|Product:||Affected Version(s):||Risk Level:||Actions:|
|Avaya Aura™ Application Enablement Services||4.2.4 and earlier||Medium||Upgrade to AES 4.2.4 and apply Super Patch 1 as detailed in PSN003161u. Alternatively customers can purchase an upgrade to AES 5.2.2 where this issue is already addressed.|
Recommended Actions for System Products:
Avaya strongly recommends that customers follow networking and security best practices by implementing firewalls, ACLs, physical security or other appropriate access restrictions. Though Avaya believes such restrictions should always be in place; risk to Avaya's product and the surrounding network from this potential vulnerability may be mitigated by ensuring these practices are implemented until such time as a product update is available or the recommended action is applied. Further restrictions as deemed necessary based on the customer's security policies may be required during this interim period.
