DATE CVE VULNERABILITY TITLE RISK
2023-12-18 CVE-2023-48795 Improper Validation of Integrity Check Value vulnerability in multiple products
The SSH transport protocol with certain OpenSSH extensions, found in OpenSSH before 9.6 and other products, allows remote attackers to bypass integrity checks such that some packets are omitted (from the extension negotiation message), and a client and server may consequently end up with a connection for which some security features have been downgraded or disabled, aka a Terrapin attack.

2012-12-04 CVE-2012-5975 Improper Authentication vulnerability in SSH Tectia Server
The SSH USERAUTH CHANGE REQUEST feature in SSH Tectia Server 6.0.4 through 6.0.20, 6.1.0 through 6.1.12, 6.2.0 through 6.2.5, and 6.3.0 through 6.3.2 on UNIX and Linux, when old-style password authentication is enabled, allows remote attackers to bypass authentication via a crafted session involving entry of blank passwords, as demonstrated by a root login session from a modified OpenSSH client with an added input_userauth_passwd_changereq call in sshconnect2.c.

2008-11-19 CVE-2008-5161 Information Exposure vulnerability in multiple products
Error handling in the SSH protocol in (1) SSH Tectia Client and Server and Connector 4.0 through 4.4.11, 5.0 through 5.2.4, and 5.3 through 5.3.8; Client and Server and ConnectSecure 6.0 through 6.0.4; Server for Linux on IBM System z 6.0.4; Server for IBM z/OS 5.5.1 and earlier, 6.0.0, and 6.0.1; and Client 4.0-J through 4.3.3-J and 4.0-K through 4.3.10-K; and (2) OpenSSH 4.7p1 and possibly other versions, when using a block cipher algorithm in Cipher Block Chaining (CBC) mode, makes it easier for remote attackers to recover certain plaintext data from an arbitrary block of ciphertext in an SSH session via unknown vectors.

2008-01-09 CVE-2007-5616 Permissions, Privileges, and Access Controls vulnerability in multiple products
ssh-signer in SSH Tectia Client and Server 5.x before 5.2.4, and 5.3.x before 5.3.6, on Unix and Linux allows local users to gain privileges via unspecified vectors.

2007-04-18 CVE-2007-2063 Permissions, Privileges, and Access Controls vulnerability in SSH Tectia Server 5.0/5.1.0/5.2.0
SSH Tectia Server for IBM z/OS before 5.4.0 uses insecure world-writable permissions for (1) the server pid file, which allows local users to cause arbitrary processes to be stopped, or (2) when _BPX_BATCH_UMASK is missing from the environment, creates HFS files with insecure permissions, which allows local users to read or modify these files and have other unknown impact.

2006-10-24 CVE-2006-5484 Remote Security vulnerability in Tectia Client
SSH Tectia Client/Server/Connector 5.1.0 and earlier, Manager 2.2.0 and earlier, and other products, when using an RSA key with exponent 3, removes PKCS-1 padding before generating a hash, which allows remote attackers to forge a PKCS #1 v1.5 signature that is signed by that RSA key and prevents Tectia from correctly verifying X.509 and other certificates that use PKCS #1, a similar issue to CVE-2006-4339.

2006-08-23 CVE-2006-4316 Local Privilege Escalation vulnerability in SSH Tectia Manager Agent Process
SSH Tectia Management Agent 2.1.2 allows local users to gain root privileges by running a program called sshd, which is obtained from a process listing when the "Restart" action is selected from the Management server GUI, which causes the agent to locate the pathname of the user's program and restart it with root privileges.
