CVE-2022-45047
CriticalSummary
The class org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider in Apache MINA SSHD versions up to 2.9.1 uses Java deserialization to load a serialized java.security.PrivateKey. It is one of several implementations that can be used for loading the host keys of an SSH server.
Risk Assessment
Exploitation of this vulnerability may lead to unauthorized access to private keys, jeopardizing the security of the SSH server and the data stored within it.
Recommendation
It is recommended to upgrade Apache MINA SSHD to a version newer than 2.9.1 to mitigate the risks associated with object deserialization.
Other vulnerabilities in Apache MINA SSHD
See all- CVE-2026-58624Medium
Vulnerability in Apache MINA SSHD (sshd-git component) allows an authenticated SSH user to execute arbitrary JGit commands, including writing files to arbitrary locations via `git archive --output`.
- CVE-2026-56624High
Improper certificate validation in Apache MINA SSHD (server-side). The server did not check for force-command or verify-required options in OpenSSH certificates, allowing an authenticated user to execute other commands than specified. Fixed in versions 2.19.0 and 3.0.0-M5.
- CVE-2026-56623High
A path traversal vulnerability in the sshd-git component of Apache MINA SSHD on Windows allows an authenticated remote user to access git repositories outside the configured server root directory. The fix for CVE-2026-48827 was partially ineffective on Windows.
- CVE-2026-56452High
Path traversal vulnerability in the sshd-scp component of Apache MINA SSHD. A malicious sender can send filenames containing paths, allowing files to be written to arbitrary locations. Affects applications using SCP to receive files.
- CVE-2026-48827High
A path traversal vulnerability in Apache MINA SSHD bundle sshd-git. Lack of path validation in git operations allows authenticated SSH users to access git repositories outside the configured git server root directory.
Original NVD description (English source)
Class org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider in Apache MINA SSHD <= 2.9.1 uses Java deserialization to load a serialized java.security.PrivateKey. The class is one of several implementations that an implementor using Apache MINA SSHD can choose for loading the host keys of an SSH server.
