A vulnerability in the administrative shell of Cisco AsyncOS on Cisco Email Security Appliance (ESA) and Content Security Management Appliance (SMA) could allow an authenticated, local attacker to escalate their privilege level and gain root access. The attacker has to have a valid user credential with at least a privilege level of a guest user. The vulnerability is due to an incorrect networking configuration at the administrative shell CLI. An attacker could exploit this vulnerability by authenticating to the targeted device and issuing a set of crafted, malicious commands at the administrative shell. An exploit could allow the attacker to gain root access on the device. Cisco Bug IDs: CSCvb34303, CSCvb35726.

Security readout for executives and security teams

CVE-2018-0095 lets a logged-in user on Cisco Email Security Appliance or Content Security Management Appliance escalate to root through the administrative shell. The issue requires valid credentials, reportedly as low as guest privilege, but root access on a mail/security appliance can create serious operational and data-security impact. Exposure is likely limited to Cisco ESA or SMA deployments where users can authenticate to the administrative shell. Risk increases where guest or low-privilege shell accounts exist, credentials are shared, or appliance administration is reachable by many operators. Treat this as high priority for any environment still running affected Cisco ESA or SMA software. It is not described as internet-remote or actively exploited here, but root access on email security infrastructure can undermine a critical control plane. Mitigation focus: Review Cisco advisory cisco-sa-20180117-esasma for affected releases and vendor fixes.; Upgrade or remediate only according to Cisco's published guidance.; Restrict administrative shell access to trusted administrators only..
