CVSS: 7.8EPSS: 0%CPEs: 2EXPL: 1CVE-2023-20178
https://notcve.org/view.php?id=CVE-2023-20178
A vulnerability in the client update process of Cisco AnyConnect Secure Mobility Client Software for Windows and Cisco Secure Client Software for Windows could allow a low-privileged, authenticated, local attacker to elevate privileges to those of SYSTEM. The client update process is executed after a successful VPN connection is established. This vulnerability exists because improper permissions are assigned to a temporary directory that is created during the update process. An attacker could exploit this vulnerability by abusing a specific function of the Windows installer process. A successful exploit could allow the attacker to execute code with SYSTEM privileges. • https://github.com/Wh04m1001/CVE-2023-20178 https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-ac-csc-privesc-wx4U4Kw • CWE-276: Incorrect Default Permissions •
CVSS: 7.8EPSS: 0%CPEs: 1EXPL: 0CVE-2021-40124 – Cisco AnyConnect Secure Mobility Client for Windows with Network Access Manager Module Privilege Escalation Vulnerability
https://notcve.org/view.php?id=CVE-2021-40124
A vulnerability in the Network Access Manager (NAM) module of Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated, local attacker to escalate privileges on an affected device. This vulnerability is due to incorrect privilege assignment to scripts executed before user logon. An attacker could exploit this vulnerability by configuring a script to be executed before logon. A successful exploit could allow the attacker to execute arbitrary code with SYSTEM privileges. Una vulnerabilidad en el módulo Network Access Manager (NAM) de Cisco AnyConnect Secure Mobility Client para Windows podría permitir a un atacante local autenticado escalar privilegios en un dispositivo afectado. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-anyconnect-nam-priv-yCsRNUGT • CWE-266: Incorrect Privilege Assignment CWE-269: Improper Privilege Management •
CVSS: 7.0EPSS: 0%CPEs: 3EXPL: 0CVE-2021-34788 – Cisco AnyConnect Secure Mobility Client for Linux and Mac OS with VPN Posture (HostScan) Module Shared Library Hijacking Vulnerability
https://notcve.org/view.php?id=CVE-2021-34788
A vulnerability in the shared library loading mechanism of Cisco AnyConnect Secure Mobility Client for Linux and Mac OS could allow an authenticated, local attacker to perform a shared library hijacking attack on an affected device if the VPN Posture (HostScan) Module is installed on the AnyConnect client. This vulnerability is due to a race condition in the signature verification process for shared library files that are loaded on an affected device. An attacker could exploit this vulnerability by sending a series of crafted interprocess communication (IPC) messages to the AnyConnect process. A successful exploit could allow the attacker to execute arbitrary code on the affected device with root privileges. To exploit this vulnerability, the attacker must have a valid account on the system. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-anyconnect-lib-hija-cAFB7x4q • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition •
CVSS: 7.0EPSS: 0%CPEs: 1EXPL: 0CVE-2021-1567 – Cisco AnyConnect Secure Mobility Client for Windows with VPN Posture (HostScan) Module DLL Hijacking Vulnerability
https://notcve.org/view.php?id=CVE-2021-1567
A vulnerability in the DLL loading mechanism 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 a race condition in the signature verification process for DLL files that are loaded on an affected device. An attacker could exploit this vulnerability by sending a series of crafted interprocess communication (IPC) messages to the AnyConnect process. A successful exploit could allow the attacker to execute arbitrary code on the affected device with SYSTEM privileges. To exploit this vulnerability, the attacker must have valid credentials on the Windows system. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-anyconnect-pos-dll-ff8j6dFv • CWE-367: Time-of-check Time-of-use (TOCTOU) Race Condition CWE-427: Uncontrolled Search Path Element •
CVSS: 5.5EPSS: 0%CPEs: 1EXPL: 0CVE-2021-1568 – Cisco AnyConnect Secure Mobility Client for Windows Denial of Service Vulnerability
https://notcve.org/view.php?id=CVE-2021-1568
A vulnerability in Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated, local attacker to cause a denial of service (DoS) condition on an affected system. This vulnerability is due to uncontrolled memory allocation. An attacker could exploit this vulnerability by copying a crafted file to a specific folder on the system. A successful exploit could allow the attacker to crash the VPN Agent service when the affected application is launched, causing it to be unavailable to all users of the system. To exploit this vulnerability, the attacker must have valid credentials on a multiuser Windows system. • https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-anyconnect-dos-hMhyDfb8 • CWE-789: Memory Allocation with Excessive Size Value •
