Cisco informed customers this week that its Prime Data Center Network Manager (DCNM) is affected by two critical vulnerabilities that can be exploited for remote code execution and to access the product’s administrative console.
One of the flaws, tracked as CVE-2017-6639, is related to the lack of authentication and authorization for a debugging tool that was inadvertently left enabled.
A remote, unauthenticated attacker can exploit the vulnerability to access sensitive information or execute arbitrary code with root privileges by connecting to the debugging tool via TCP.
The security hole affects Cisco Prime DCNM releases 10.1(1) and 10.1(2) for Windows, Linux and virtual appliances.
The second Prime DCNM vulnerability, identified as CVE-2017-6640, exists due to a default user account protected by a static password. An attacker who can remotely connect to the affected system can use this account to gain privileged access to the server’s administration interface.
The networking giant said this flaw only affects Prime DCNM running software version 10.2(1) for Windows, Linux and virtual appliances.
Both DCNM vulnerabilities were disclosed to Cisco by Antonius Mulder of Commonwealth Bank of Australia and there is no evidence that they have been exploited in the wild. The flaws have been patched with the release of version 10.2(1), but workarounds are not available.
Cisco has also published an advisory for a high severity local privilege escalation vulnerability affecting AnyConnect Secure Mobility Client for Windows versions prior to 4.4.02034. The security hole, reported by Felix Wilhelm of ERNW, allows a local attacker to install and execute a file with SYSTEM privileges.
Another advisory describes a high severity denial-of-service (DoS) vulnerability in the Session Initiation Protocol (SIP) of the Cisco TelePresence Codec (TC) and Collaboration Endpoint (CE) software. A remote, unauthenticated attacker can exploit this flaw to cause a DoS condition by sending a flood of SIP INVITE packets to the vulnerable device.
The weakness, reported to Cisco by Knud Hojgaard of F-Secure, affects several TelePresence MX, Profile, SX, System Profile MXP, System EX, and Integrator C series products. Two Collaboration Desk Endpoint DX series devices are also impacted.
