Check Point Firewall-1 allows remote attackers to bypass port access restrictions on an FTP server by forcing it to send malicious packets that Firewall-1 misinterprets as a valid 227 response to a client's PASV attempt.
CVE-2001-1065 1 Cisco 1 Cbos 2026-04-16 N/A
Web-based configuration utility in Cisco 600 series routers running CBOS 2.0.1 through 2.4.2ap binds itself to port 80 even when web-based configuration services are disabled, which could leave the router open to attack.

Cisco PIX Firewall 6.0.3 and earlier, and 6.1.x to 6.1.3, do not delete the duplicate ISAKMP SAs for a user's VPN session, which allows local users to hijack a session via a man-in-the-middle attack.
CVE-2000-0380 1 Cisco 1 Ios 2026-04-16 N/A
The IOS HTTP service in Cisco routers and switches running IOS 11.1 through 12.1 allows remote attackers to cause a denial of service by requesting a URL that contains a %% string.
CVE-2002-1359 7 Cisco, Fissh, Intersoft and 4 more 7 Ios, Ssh Client, Securenetterm and 4 more 2026-04-16 N/A
Multiple SSH2 servers and clients do not properly handle large packets or large fields, which may allow remote attackers to cause a denial of service or possibly execute arbitrary code via buffer overflow attacks, as demonstrated by the SSHredder SSH protocol test suite.
CVE-1999-1582 1 Cisco 1 Pix Firewall 2026-04-16 N/A
By design, the "established" command on the Cisco PIX firewall allows connections from one host to arbitrary ports of a target host if an alternative conduit has already been allowed, which can cause administrators to configure less restrictive access controls than intended if they do not understand this functionality.

CVE-2002-1106 1 Cisco 1 Vpn Client 2026-04-16 N/A
Cisco Virtual Private Network (VPN) Client software 2.x.x, and 3.x before 3.5.1C, does not properly verify that certificate DN fields match those of the certificate from the VPN Concentrator, which allows remote attackers to conduct man-in-the-middle attacks.
CVE-2002-1105 1 Cisco 1 Vpn Client 2026-04-16 N/A
Cisco Virtual Private Network (VPN) Client software 2.x.x, and 3.x before 3.5.1C, allows local users to use a utility program to obtain the group password.
CVE-2001-0041 1 Cisco 1 Catos 2026-04-16 N/A
