CVSS v3.1 |
| 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 Multimedia Communication Server (MSC) 5100 3.0.13 does not verify credentials during call placement, which allows remote attackers to spoof and redirect VoIP calls, possibly related to the snoop command. |
| 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. |
| Unspecified vulnerability in the "session limitation technique" in the FTP service on Nortel Communications Server 1000 (CS1K) 4.50.x, when running on VGMC or signaling nodes, allows remote attackers to cause a denial of service (resource exhaustion and failed updates) via unknown vectors that causes consumption of all available sessions. |
| Nortel MG1000S, Signaling Server, and Call Server on the Communications Server 1000 (CS1K) 4.50.x contain multiple unspecified hard-coded accounts and passwords, which allows remote attackers to gain privileges. |
| cgiproc CGI script in Nortel Contivity HTTP server allows remote attackers to cause a denial of service via a malformed URL that includes shell metacharacters. |
| The Nautica Marlin bridge allows remote attackers to cause a denial of service via a zero length UDP packet to the SNMP port. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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. |
| 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 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. |
| 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. |
| 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 Router (aka Contivity) allows remote attackers to cause a denial of service (crash) via an IPsec IKE packet with a malformed ISAKMP header. |
| 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. |
