Nortel VPN Router (aka Contivity) 1000, 2000, 4000, and 5000 before 5_05.149, 5_05.3xx before 5_05.304, and 6.x before 6_05.140 includes the FIPSecryptedtest1219 and FIPSunecryptedtest1219 default accounts in the LDAP template, which might allow remote attackers to access the private network.
CVE-2005-0844 1 Nortel 1 Contivity 2025-04-03 4.6 MEDIUM N/A
Nortel VPN client 5.01 stores the cleartext password in the memory of the Extranet.exe process, which could allow local users to obtain sensitive information.
CVE-2004-2621 1 Nortel 1 Contivity 2025-04-03 4.0 MEDIUM N/A
Nortel Contivity VPN Client 2.1.7, 3.00, 3.01, 4.91, and 5.01, when opening a VPN tunnel, does not check the gateway certificate until after a dialog box has been displayed to the user, which creates a race condition that allows remote attackers to perform a man-in-the-middle (MITM) attack.
CVE-2004-1305 2 Microsoft, Nortel 19 Windows 2000, Windows 2003 Server, Windows 98 and 16 more 2025-04-03 5.0 MEDIUM N/A
The Windows Animated Cursor (ANI) capability in Windows NT, Windows 2000 through SP4, Windows XP through SP1, and Windows 2003 allow remote attackers to cause a denial of service via (1) the frame number set to zero, which causes an invalid memory address to be used and leads to a kernel crash, or (2) the rate number set to zero, which leads to resource exhaustion and hang.
CVE-2004-1319 2 Microsoft, Nortel 9 Windows 2000, Windows 2003 Server, Windows 98 and 6 more 2025-04-03 5.0 MEDIUM N/A
The DHTML Edit Control (dhtmled.ocx) allows remote attackers to inject arbitrary web script into other domains by setting a name for a window, opening a child page whose target is the window with the given name, then injecting the script from the parent into the child using execScript, as demonstrated by "AbusiveParent" in Internet Explorer 6.0.2900.2180.
CVE-2000-0009 1 Nortel 1 Optivity Net Architect 2025-04-03 7.2 HIGH N/A

Multiple TCP implementations with Protection Against Wrapped Sequence Numbers (PAWS) with the timestamps option enabled allow remote attackers to cause a denial of service (connection loss) via a spoofed packet with a large timer value, which causes the host to discard later packets because they appear to be too old.
CVE-2005-2579 1 Nortel 1 Contivity 2025-04-03 7.2 HIGH N/A
Nortel Contivity VPN Client V05_01.030, when configuring a certificate to be used as authentication, does not properly drop system privileges, which allows local users to gain privileges by opening a program with the File Open dialog box.
