CVE-2023-32322
No affected components available
Ombi is an open source application which allows users to request specific media from popular self-hosted streaming servers. Versions prior to 4.38.2 contain an arbitrary file read vulnerability where an Ombi administrative user may access files available to the Ombi server process on the host operating system. Ombi administrators may not always be local system administrators and so this may violate the security expectations of the system. The arbitrary file read vulnerability was present in ReadLogFile and Download endpoints in SystemControllers.cs as the parameter logFileName is not sanitized before being combined with the Logs directory. When using Path.Combine(arg1, arg2, arg3), an attacker may be able to escape to folders/files outside of Path.Combine(arg1, arg2) by using ".." in arg3. In addition, by specifying an absolute path for arg3, Path.Combine will completely ignore the first two arguments and just return just arg3. This vulnerability can lead to information disclosure. The Ombi documentation suggests running Ombi as a Service with Administrator privileges. An attacker targeting such an application may be able to read the files of any Windows user on the host machine and certain system files. This issue has been addressed in commit b8a8f029 and in release version 4.38.2. Users are advised to upgrade. There are no known workarounds for this vulnerability. This issue is also tracked as GHSL-2023-088.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker needs high-level or administrative privileges. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the confidentiality of the information.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
