Hi David, Logback does NOT offer a lookup mechanism at the message level. So it is safe with respect to CVE-2021-44228. However, we are still looking at other venues for other attacks. Best regards, -- Ceki Gülcü Please contact sales@qos.ch for support related to SLF4J or logback projects. On 12/12/2021 12:00, David Roussel wrote:
There are two possible interpretations of your question
a. Do any similar vulnerabilities exist in logback and slf4j
b. Have any similar vulnerabilities been detected and reported in logback and slf4j
In the case of (a) we don’t know,, since any piece of normal-complexity software can contain vulnerabilities. In general you can only prove that vulnerabilities exist, not that they don’t exist. But this is more of a philosophical question.
In the case of (b); if they had been detected and reported, they would be listed in the various CVE databases, for example: - https://security.snyk.io/search?q=logback - https://security.snyk.io/search?q=slf4j - … and others
For your particular configuration, and set of transitive dependencies, you need to investigate yourself.
