1.6 Virsec Security Platform (VSP) Support Given the severity of vulnerability and with exploit available publicly, all the Apache Tomcat servers are at high risk. This site also has hacking tutorial that helps exploiting Java deserialization vulnerabilities.
#Apache tomcat 8 classpath software#
Given that Apache Tomcat powers a broad range of web applications across countless industries and use cases, from Fortune 500 conglomerates to service providers to eCommerce systems, it is reasonable to estimate that 10s of millions of this software are in use.īased on the link here, large range of versions of tomcat are affected. Tomcat has 60% market share of Java Application servers. Based on this link from 2010, Apache Tomcat has been downloaded 10 Million times.

gadgets).Ī publicly disclosed exploit code is available here.
There must be libraries on the class path which are vulnerable to be exploited by a Java deserialization attack (e.g. The attacker must find a separate file upload vulnerability to place the malicious serialized file on the server. This is likely to happen only on websites with high traffic loads (but not too high, as it will be more likely that a JDBC Store is used instead of a File Store) PersistentManager needs to be enabled manually by the tomcat administrator. This attack can have high impact (RCE), but the conditions that need to be met make the likelihood of exploitation low. Serialized object on disk and have the PersistentManager load from there. The idea is to have the attacker store a malicious These session objects are stored as serialized object. The vulnerability exists because the PersistentManager will try to load session objects from disk. The CVSS Base Score is 7.0 (High) 1.3 Affected Version Watch the video to learn more about this and other important vulnerabilities. There are gadgets in the classpath that can be used for a Java deserialization attack. The attacker can upload a file with arbitrary content, has control over the filename and knows the location where it is uploaded. The “PersistentManager” is enabled and it’s using a “FileStore”. There are several prerequisites for this vulnerability to be exploitable. 1.1 Vulnerability SummaryĪ new remote code execution vulnerability was disclosed for Apache Tomcat.
