CVE-2026-42084
HighSummary
OpenC3 COSMOS prior to versions 6.10.5 and 7.0.0-rc3 allowed users to change their password without providing the old password, accepting only a valid session token. This behavior can be exploited by an attacker who has a valid session token to hijack accounts and block legitimate users from accessing their accounts.
Risk Assessment
The organization may be at risk of account takeover, including administrative accounts, leading to loss of control over the system and data. Attackers can gain persistent access to accounts, posing a serious security threat.
Recommendation
It is recommended to upgrade to versions 6.10.5 or 7.0.0-rc3 to mitigate this vulnerability. Additionally, implementing extra security measures, such as user identity verification when changing passwords, is advisable.
Other vulnerabilities in OpenC3 COSMOS
Original NVD description (English source)
OpenC3 COSMOS provides the functionality needed to send commands to and receive data from one or more embedded systems. Prior to versions 6.10.5 and 7.0.0-rc3, the OpenC3 password change functionality allows a user to change their password without providing the old password, by accepting a valid session token instead. In assumed breach scenarios, this behaviour can be exploited by an attacker who has already obtained a valid session token, to gain persistence in hijacked account (including admin) and prevent legitimate users from accessing the account. This issue has been patched in versions 6.10.5 and 7.0.0-rc3.
