CVE-2025-20206 [HIGH] CWE-347 CVE-2025-20206: A vulnerability in the interprocess communication (IPC) channel of Cisco Secure Client for Windows c A vulnerability in the interprocess communication (IPC) channel of Cisco Secure Client for Windows could allow an authenticated, local attacker to perform a DLL hijacking attack on an affected device if the Secure Firewall Posture Engine, formerly HostScan, is installed on Cisco Secure Client. This vulnerability is due to insufficient validation of r

CVE-2020-3432 [MEDIUM] CWE-59 CVE-2020-3432: A vulnerability in the uninstaller component of Cisco AnyConnect Secure Mobility Client for Mac OS c A vulnerability in the uninstaller component of Cisco AnyConnect Secure Mobility Client for Mac OS could allow an authenticated, local attacker to corrupt the content of any file in the filesystem. The vulnerability is due to the incorrect handling of directory paths. An attacker could exploit this vulnerability by creating a symbolic link (symlink) to

CVE-2024-20474 [MEDIUM] CWE-191 CVE-2024-20474: A vulnerability in Internet Key Exchange version 2 (IKEv2) processing of Cisco Secure Client Softwar A vulnerability in Internet Key Exchange version 2 (IKEv2) processing of Cisco Secure Client Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) of Cisco Secure Client. This vulnerability is due to an integer underflow condition. An attacker could exploit this vulnerability by sending a crafted IKEv2 packet to

CVE-2024-20391 [MEDIUM] CWE-306 CVE-2024-20391: A vulnerability in the Network Access Manager (NAM) module of Cisco Secure Client could allow an una A vulnerability in the Network Access Manager (NAM) module of Cisco Secure Client could allow an unauthenticated attacker with physical access to an affected device to elevate privileges to SYSTEM. This vulnerability is due to a lack of authentication on a specific function. A successful exploit could allow the attacker to execute arbitrary code wit

CVE-2024-20337 [HIGH] CWE-93 CVE-2024-20337: A vulnerability in the SAML authentication process of Cisco Secure Client could allow an unauthentic A vulnerability in the SAML authentication process of Cisco Secure Client could allow an unauthenticated, remote attacker to conduct a carriage return line feed (CRLF) injection attack against a user. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by persuading a user to click a

CVE-2024-20338 [HIGH] CWE-427 CVE-2024-20338: A vulnerability in the ISE Posture (System Scan) module of Cisco Secure Client for Linux could allow A vulnerability in the ISE Posture (System Scan) module of Cisco Secure Client for Linux could allow an authenticated, local attacker to elevate privileges on an affected device. This vulnerability is due to the use of an uncontrolled search path element. An attacker could exploit this vulnerability by copying a malicious library file to a specific di
