What is CVE-2023-25826?
CVE-2023-25826 is a critical command injection vulnerability in OpenTSDB, published on 3 May 2023. An attacker can exploit it over the internet without logging in, with no action from the victim.
Official description
Due to insufficient validation of parameters passed to the legacy HTTP query API, it is possible to inject crafted OS commands into multiple parameters and execute malicious code on the OpenTSDB host system. This exploit exists due to an incomplete fix that was made when this vulnerability was previously disclosed as CVE-2020-35476. Regex validation that was implemented to restrict allowed input to the query API does not work as intended, allowing crafted commands to bypass validation.
Weakness: CWE-78
