Two critical security flaws uncovered in the open up-supply CasaOS own cloud software could be effectively exploited by attackers to attain arbitrary code execution and choose more than susceptible programs.
The vulnerabilities, tracked as CVE-2023-37265 and CVE-2023-37266, the two carry a CVSS score of 9.8 out of a maximum of 10.
Sonar security researcher Thomas Chauchefoin, who uncovered the bugs, claimed they “let attackers to get about authentication demands and attain full entry to the CasaOS dashboard.”

Even far more troublingly, CasaOS’ support for third-party apps could be weaponized to run arbitrary commands on the program to obtain persistent accessibility to the machine or pivot into inside networks.
Adhering to responsible disclosure on July 3, 2023, the flaws have been resolved in edition .4.4 produced by its maintainers IceWhale on July 14, 2023.
A short description of the two flaws is as follows –
- CVE-2023-37265 – Incorrect identification of the resource IP tackle, allowing unauthenticated attackers to execute arbitrary commands as root on CasaOS instances
- CVE-2023-37265 – Unauthenticated attackers can craft arbitrary JSON Web Tokens (JWTs) and obtain attributes that involve authentication and execute arbitrary instructions as root on CasaOS instances
A consequence of profitable exploitation of the aforementioned flaws could allow for attackers to get about authentication restrictions and get administrative privileges on susceptible CasaOS situations.
“In normal, identifying IP addresses at the application layer is risk-vulnerable and should not be relied on for security choices,” Chauchefoin explained.
“Quite a few diverse headers could transport this information (X-Forwarded-For, Forwarded, and many others.), and the language APIs sometimes need to interpret nuances of the HTTP protocol the exact same way. Equally, all frameworks have their very own quirks and can be difficult to navigate devoid of skilled know-how of these common security footguns.”
