Octopus Server: Insertion of Sensitive Information into Log File

CVE-2023-1904 is a high-severity insertion of sensitive information into log file vulnerability in Octopus Server from Octopus Deploy, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 2023.1.11942, 2023.2.13151, 2023.3.5049 as the first without the flaw, so updating Octopus Server to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.39% chance of exploitation within 30 days, which is low compared with other CVEs.

What to do

  1. Update Octopus Server to 2023.1.11942 or 2023.2.13151 or 2023.3.5049, whichever matches your release line, or a later version.
