    Deserialization of Untrusted Data

    ch.qos.logback:logback-classic is a reliable, generic, fast and flexible logging library for Java.

    Affected versions of this package are vulnerable to Deserialization of Untrusted Data in HardenedObjectInputStream, whose resolveClass allowlist admitted any class whose name starts with java.lang or java.util rather than matching specific authorized classes. An attacker can instantiate dangerous classes such as java.lang.ProcessBuilder during deserialization, reaching remote code execution through a gadget chain, by delivering a malicious serialized object to a logback component that deserializes it, such as its socket receiver for serialized logging events (SocketNode). Exploitation requires the application to deserialize attacker-controlled serialized data through logback, in practice via its socket-based receiver, together with a usable gadget class on the classpath.

    How to fix Deserialization of Untrusted Data?

    Upgrade ch.qos.logback:logback-classic to version 1.5.33 or higher.

    Improper Neutralization of Special Elements

    ch.qos.logback:logback-classic is a reliable, generic, fast and flexible logging library for Java.

    Affected versions of this package are vulnerable to Improper Neutralization of Special Elements via the JaninoEventEvaluator extension. An attacker can execute arbitrary code by compromising an existing logback configuration file or injecting an environment variable before program execution.

    How to fix Improper Neutralization of Special Elements?

    Upgrade ch.qos.logback:logback-classic to version 1.3.15, 1.5.13 or higher.

    Denial of Service (DoS)

    ch.qos.logback:logback-classic is a reliable, generic, fast and flexible logging library for Java.

    Affected versions of this package are vulnerable to Denial of Service (DoS). An attacker can mount a denial-of-service attack by sending poisoned data. This is only exploitable if logback receiver component is deployed.

    How to fix Denial of Service (DoS)?

    Upgrade ch.qos.logback:logback-classic to version 1.2.13, 1.3.12, 1.4.12 or higher.
