CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 1CVE-2021-1366 – Cisco AnyConnect Secure Mobility Client for Windows with VPN Posture (HostScan) Module DLL Hijacking Vulnerability
https://notcve.org/view.php?id=CVE-2021-1366
A vulnerability in the interprocess communication (IPC) channel of Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated, local attacker to perform a DLL hijacking attack on an affected device if the VPN Posture (HostScan) Module is installed on the AnyConnect client. This vulnerability is due to insufficient validation of resources that are loaded by the application at run time. An attacker could exploit this vulnerability by sending a crafted IPC message to the AnyConnect process. A successful exploit could allow the attacker to execute arbitrary code on the affected machine with SYSTEM privileges. To exploit this vulnerability, the attacker needs valid credentials on the Windows system. • https://github.com/koztkozt/CVE-2021-1366 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-anyconnect-dll-hijac-JrcTOQMC • CWE-347: Improper Verification of Cryptographic Signature CWE-427: Uncontrolled Search Path Element •
CVSS: 5.5EPSS: 0%CPEs: 5EXPL: 0CVE-2021-1258 – Cisco AnyConnect Secure Mobility Client Arbitrary File Read Vulnerability
https://notcve.org/view.php?id=CVE-2021-1258
A vulnerability in the upgrade component of Cisco AnyConnect Secure Mobility Client could allow an authenticated, local attacker with low privileges to read arbitrary files on the underlying operating system (OS) of an affected device. The vulnerability is due to insufficient file permission restrictions. An attacker could exploit this vulnerability by sending a crafted command from the local CLI to the application. A successful exploit could allow the attacker to read arbitrary files on the underlying OS of the affected device. The attacker would need to have valid user credentials to exploit this vulnerability. • https://kc.mcafee.com/corporate/index?page=content&id=SB10382 https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-anyconnect-fileread-PbHbgHMj • CWE-264: Permissions, Privileges, and Access Controls CWE-269: Improper Privilege Management •
CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2021-1237 – Cisco AnyConnect Secure Mobility Client for Windows DLL Injection Vulnerability
https://notcve.org/view.php?id=CVE-2021-1237
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. 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. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-anyconnect-dll-injec-pQnryXLf • CWE-427: Uncontrolled Search Path Element •
