The vulnerability has actually affected a broad variety of companies as the log4j library is commonly utilized, and the defect can be quickly made use of to burglarize systems, take information, and contaminate networks with destructive software application.

Numerous widely-used web servers such as Tomcat and Jetty are composed in Java however do not utilize the log4j library by default so are not straight impacted by the problem. Nevertheless, they can be set up to do so, and it is likewise possible that websites that utilize popular web servers composed in other languages – Apache and nginx are composed in C, for example – might still utilize the susceptible library at some level in their innovation stack.

Numerous less widely known servers incorporate the log4j library straight, such as IBM WebSphere. Numerous WebSphere parts such as the Admin Console utilize the library therefore are susceptible to the problem, while applications served utilizing WebSphere might be susceptible if they utilize the library.
