CVE-2021-31352 is a medium-severity vulnerability rated 5.3/10 on the CVSS scale. An Information Exposure vulnerability in Juniper Networks SRC Series devices configured for NETCONF over SSH permits the negotiation of weak ciphers, which could allow a remote attacker to obtain sensitive information. A remote attacker with read and write access to network data could exploit this vulnerability to display plaintext bits from a block of ciphertext and obtain sensitive information. EPSS estimates a 0.81% chance of exploitation in the next 30 days.

Description
