-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 =========================================================================== AUSCERT External Security Bulletin Redistribution ESB-2015.2190 Cisco Prime Infrastructure Privilege Escalation Vulnerability 21 August 2015 =========================================================================== AusCERT Security Bulletin Summary --------------------------------- Product: Cisco Prime Infrastructure Publisher: Cisco Systems Operating System: Cisco Impact/Access: Increased Privileges -- Existing Account Resolution: Mitigation CVE Names: CVE-2015-4331 Original Bulletin: http://tools.cisco.com/security/center/viewAlert.x?alertId=40553 - --------------------------BEGIN INCLUDED TEXT-------------------- Vulnerability Alert Cisco Prime Infrastructure Privilege Escalation Vulnerability Threat Type: CWE-264: Permissions, Privileges, and Access Control IntelliShield ID: 40553 Version: 1 First Published: 2015 August 20 13:45 GMT Last Published: 2015 August 20 13:45 GMT Port: Not available CVE: CVE-2015-4331 Urgency: Unlikely Use Credibility: Confirmed Severity: Mild Damage CVSS Base: 4.0 CVSS Version 2.0 CVSS Temporal: 3.8 Version Summary: Cisco Prime Infrastructure contains a vulnerability that could allow an authenticated, remote attacker to gain elevated privileges on a targeted application. Updates are not available. Description A vulnerability in the Cisco Prime Infrastructure (PI) username storage and authentication process could allow an authenticated, remote attacker to gain elevated privileges on a targeted system. The vulnerability occurs because the affected software saves case-sensitive usernames and performs case-sensitive string comparisons. An attacker could exploit this vulnerability during authentication by entering a username that contains characters in cases different from the combination registered on the affected software. If the Cisco PI is configured for external authentication using a AAA server, the login will succeed but the affected software will assign default authorizations to the user who is logged in. A successful exploit could allow the attacker to access the targeted system and elevate privileges in the application. Cisco has confirmed the vulnerability; however, software updates are not available. Warning Indicators Cisco Prime Infrastructure versions 1.4(0.45) and prior are vulnerable. IntelliShield Analysis To exploit this vulnerability, an attacker must authenticate to the targeted device. A successful exploit could be accomplished if the affected software is configured for external authentication. These access requirements reduce the likelihood of a successful exploit. Cisco indicates through the CVSS score that functional exploit code exists; however, the code is not known to be publicly available. Vendor Announcements Cisco has released bug ID CSum59958 for registered users, which contains additional details and an up-to-date list of affected product versions. Impact An authenticated, remote attacker could exploit this vulnerability to gain elevated privileges on a targeted system. Technical Information The vulnerability occurs because the affected software saves case-sensitive usernames and performs case-sensitive username string comparisons. An attacker could exploit this vulnerability during authentication by entering a username that contains characters in cases different from the combination registered on the affected software. A successful exploit could allow the attacker to access the targeted system, elevate privileges in the application, and conduct further attacks.
