Cisco addressed tens of high-severity flaws, including some flaws in the AnyConnect Secure Mobility Client and in its small business routers.

This week Cisco released security updates to address 67 high-severity vulnerabilities, including issues affecting Cisco’s AnyConnect Secure Mobility Client and small business routers (i.e. Cisco RV110W, RV130, RV130W, and RV215W). One of the flaws fixed by the tech giant, tracked as CVE-2021-1144, is a high-severity vulnerability that affects Cisco Connected Mobile Experiences (CMX), which is a smart Wi-Fi solution that uses the Cisco wireless infrastructure to provide location services and location analytics for consumers’ mobile devices. CMX supports your organization’s Wi-Fi and mobile engagement and allows them to directly deliver content to smartphones and tablets that are personalized to visitors’ preferences and pertinent to their real-time indoor locations.

The vulnerability, which received a CVSS score of 8.8 out of 10, could be exploited by a remote authenticated attacker to change the password for any account user on affected systems.

“A vulnerability in Cisco Connected Mobile Experiences (CMX) could allow a remote, authenticated attacker without administrative privileges to alter the password of any user on an affected system.” reads the advisory published by Cisco.

“The vulnerability is due to incorrect handling of authorization checks for changing a password. An authenticated attacker without administrative privileges could exploit this vulnerability by sending a modified HTTP request to an affected device. A successful exploit could allow the attacker to alter the passwords of any user on the system, including an administrative user, and then impersonate that user.”

The flaw affects Cisco CMX releases 10.6.0, 10.6.1, and 10.6.2.

The vendor addressed the flaw with the release of 10.6.3 software version, it also informed customers that are no workarounds that address this issue.

Cisco also addressed a DLL Injection flaw, tracked as CVE-2021-1237, in Cisco AnyConnect Secure Mobility Client for Windows.

The flaw received a CVSS score of 7.8, attackers could exploit it to conduct a dynamic-link library (DLL) injection attack.

“A vulnerability in the Network Access Manager and Web Security Agent components of Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated, local attacker to perform a DLL injection attack. To exploit this vulnerability, the attacker would need to have valid credentials on the Windows system.” reads the advisory.

“The vulnerability is due to insufficient validation of resources that are loaded by the application at run time. An attacker could exploit this vulnerability by inserting a configuration file in a specific path in the system which, in turn, causes a malicious DLL file to be loaded when the application starts. A successful exploit could allow the attacker to execute arbitrary code on the affected machine with SYSTEM privileges.”

Cisco also fixed a series of flaws in Small Business RV110W, RV130, RV130W, and RV215W Routers Management Interface that could lead remote command execution and denial of service attacks.
