Last modified
CVE-2023-28113 is a medium-severity vulnerability rated 5.9/10 on the CVSS scale. russh is a Rust SSH client and server library. Starting in version 0.34.0 and prior to versions 0.36.2 and 0.37.1, Diffie-Hellman key validation is insufficient, which can lead to insecure shared secrets and therefore breaks confidentiality. EPSS estimates a 0.62% chance of exploitation in the next 30 days.
Description
russh is a Rust SSH client and server library. Starting in version 0.34.0 and prior to versions 0.36.2 and 0.37.1, Diffie-Hellman key validation is insufficient, which can lead to insecure shared secrets and therefore breaks confidentiality. Connections between a russh client and server or those of a russh peer with some other misbehaving peer are most likely to be problematic. These may vulnerable to eavesdropping. Most other implementations reject such keys, so this is mainly an interoperability issue in such a case. This issue is fixed in versions 0.36.2 and 0.37.1
