CVSS v3.1 |
| Nortel VPN Router (aka Contivity) 1000, 2000, 4000, and 5000 before 6_05.140 uses a fixed DES key to encrypt passwords, which allows remote authenticated users to obtain a password via a brute force attack on a hash from the LDAP store. |
| 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 has two template HTML files lacking certain verification tags, which allows remote attackers to access the administration interface and change the device configuration via certain requests. |
| Multiple unspecified vulnerabilities in Nortel Communication Server 1000 4.50.x allow remote attackers to execute arbitrary commands to gain privileges, obtain sensitive information, or cause a denial of service via unknown vectors. |
| Buffer overflow in the Multimedia PC Client in Nortel Multimedia Communication Server (MCS) before Maintenance Release 3.5.8.3 and 4.0.25.3 allows remote attackers to cause a denial of service (crash) via a flood of "extraneous" messages, as demonstrated by the Nessus "Generic flood" denial of service plugin. |
| Nortel UNIStim protocol, as used in Communication Server 1000 and other products, uses predictable sequence numbers, which allows remote attackers to hijack sessions via sniffing or brute force attacks. |
| 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. |
| The Session Initiation Protocol (SIP) implementation in Nortel Networks Succession Communication Server 2000, when using SIP-T, allows remote attackers to cause a denial of service and possibly execute arbitrary code via crafted INVITE messages, as demonstrated by the OUSPG PROTOS c07-sip test suite. |
| Internet Explorer in Windows XP SP2, and other versions including 5.01 and 5.5, allows remote attackers to install arbitrary programs via a web page that uses certain styles and the AnchorClick behavior, popup windows, and drag-and-drop capabilities to drop the program in the local startup folder, as demonstrated by "wottapoop.html". |
| tunnelform.yaws in Nortel SSL VPN 4.2.1.6 allows remote attackers to execute arbitrary commands via a link in the a parameter, which is executed with extra privileges in a cryptographically signed Java Applet. |
| The bna_pass program in Optivity NETarchitect uses the PATH environmental variable for finding the "rm" program, which allows local users to execute arbitrary commands. |
| 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. |
| Nortel Alteon ACEdirector WebOS 9.0, with the Server Load Balancing (SLB) and Cookie-Based Persistence features enabled, allows remote attackers to determine the real IP address of a web server with a half-closed session, which causes ACEdirector to send packets from the server without changing the address to the virtual IP address. |
| Nortel VPN Router (aka Contivity) allows remote attackers to cause a denial of service (crash) via an IPsec IKE packet with a malformed ISAKMP header. |
| Nortel CVX 1800 is installed with a default "public" community string, which allows remote attackers to read usernames and passwords and modify the CVX configuration. |
| Multiple vulnerabilities in the H.323 protocol implementation for Nortel Networks Business Communications Manager (BCM), Succession 1000 IP Trunk and IP Peer Networking, and 802.11 Wireless IP Gateway allow remote attackers to cause a denial of service and possibly execute arbitrary code, as demonstrated by the NISCC/OUSPG PROTOS test suite for the H.225 protocol. |
| 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. |
| Nortel Wireless LAN (WLAN) Access Point (AP) 2220, 2221, and 2225 allow remote attackers to cause a denial of service (service crash) via a TCP request with a large string, followed by 8 newline characters, to (1) the Telnet service on TCP port 23 and (2) the HTTP service on TCP port 80, possibly due to a buffer overflow. |
| Nortel Networks Contivity VPN Client displays a different error message depending on whether the username is valid or invalid, which could allow remote attackers to gain sensitive information. |
| 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. |
| cgiproc CGI script in Nortel Contivity HTTP server allows remote attackers to read arbitrary files by specifying the filename in a parameter to the script. |
