In WS_FTP Server versions prior to 8.7.4 and 8.8.2, a pre-authenticated attacker could leverage a .NET deserialization vulnerability in the Ad Hoc Transfer module to execute remote commands on the underlying WS_FTP Server operating system.

A privilege escalation vulnerability exists in SolarWinds Serv-U before 15.1.7 for Linux.

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. This occurs because the SSH Binary Packet Protocol (BPP), implemented by these extensions, mishandles the handshake phase and mishandles use of sequence numbers. For example, there is an effective attack against SSH's use of ChaCha20-Poly1305 (and CBC with Encrypt-then-MAC). The bypass occurs in chacha20-poly1305@openssh.com and (if CBC is used) the -etm@openssh.com MAC algorithms. This also affects Maverick Synergy Java SSH API before 3.1.0-SNAPSHOT, Dropbear through 2022.83, Ssh before 5.1.1 in Erlang/OTP, PuTTY before 0.80, AsyncSSH before 2.14.2, golang.org/x/crypto before 0.17.0, libssh before 0…

JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions.

In WS_FTP Server versions before 8.8.9 (2022.0.9), an Incorrect Implementation of Authentication Algorithm in the Web Transfer Module allows users to skip the second-factor verification and log in with username and password only.

In WS_FTP Server versions before 8.8.8 (2022.0.8), a Missing Critical Step in Multi-Factor Authentication of the Web Transfer Module allows users to skip the second-factor verification and log in with username and password only.

In WS_FTP Server versions before 8.8.8 (2022.0.8), an Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') vulnerability in the Web Transfer Module allows File Discovery, Probe System Files, User-Controlled Filename, Path Traversal.   An authenticated file download flaw has been identified where a user can craft an API call that allows them to download a file from an arbitrary folder on the drive where that user host's root folder is located (by default this is C:)

In WS_FTP Server versions before 8.8.5, reflected cross-site scripting issues have been identified on various user supplied inputs on the WS_FTP Server administrative interface.
