CVSS: 9.8EPSS: 21%CPEs: 3EXPL: 4CVE-2022-33980 – Apache Commons Configuration insecure interpolation defaults
https://notcve.org/view.php?id=CVE-2022-33980
Apache Commons Configuration performs variable interpolation, allowing properties to be dynamically evaluated and expanded. The standard format for interpolation is "${prefix:name}", where "prefix" is used to locate an instance of org.apache.commons.configuration2.interpol.Lookup that performs the interpolation. Starting with version 2.4 and continuing through 2.7, the set of default Lookup instances included interpolators that could result in arbitrary code execution or contact with remote servers. These lookups are: - "script" - execute expressions using the JVM script execution engine (javax.script) - "dns" - resolve dns records - "url" - load values from urls, including from remote servers Applications using the interpolation defaults in the affected versions may be vulnerable to remote code execution or unintentional contact with remote servers if untrusted configuration values are used. Users are recommended to upgrade to Apache Commons Configuration 2.8.0, which disables the problematic interpolators by default. • https://github.com/HKirito/CVE-2022-33980 https://github.com/tangxiaofeng7/CVE-2022-33980-Apache-Commons-Configuration-RCE https://github.com/sammwyy/CVE-2022-33980-POC https://github.com/P0lar1ght/CVE-2022-33980-POC http://www.openwall.com/lists/oss-security/2022/07/06/5 http://www.openwall.com/lists/oss-security/2022/11/15/4 https://lists.apache.org/thread/tdf5n7j80lfxdhs2764vn0xmpfodm87s https://security.netapp.com/advisory/ntap-20221028-0015 https://www.debian.org/security/20 •
CVSS: 10.0EPSS: 0%CPEs: 14EXPL: 0CVE-2020-1953 – apache-commons-configuration: uncontrolled class instantiation when loading YAML files
https://notcve.org/view.php?id=CVE-2020-1953
Apache Commons Configuration uses a third-party library to parse YAML files which by default allows the instantiation of classes if the YAML includes special statements. Apache Commons Configuration versions 2.2, 2.3, 2.4, 2.5, 2.6 did not change the default settings of this library. So if a YAML file was loaded from an untrusted source, it could therefore load and execute code out of the control of the host application. Apache Commons Configuration usa una biblioteca de terceros para analizar archivos YAML, la cual por defecto permite la instanciación de clases si el YAML incluye sentencias especiales. Apache Commons Configuration versiones 2.2, 2.3, 2.4, 2.5, 2.6 no cambió la configuración predeterminada de esta biblioteca. • https://lists.apache.org/thread.html/d0e00f2e147a9e9b13a6829133092f349b2882bf6860397368a52600%40%3Cannounce.tomcat.apache.org%3E https://lists.apache.org/thread.html/r16a2e949e35780c8974cf66104e812410f3904f752df6b66bf292269%40%3Ccommits.servicecomb.apache.org%3E https://lists.apache.org/thread.html/rde2186ad6ac0d6ed8d51af7509244adcf1ce0f9a3b7e1d1dd3b64676%40%3Ccommits.camel.apache.org%3E https://www.oracle.com/security-alerts/cpuoct2020.html https://access.redhat.com/security/cve/CVE-2020-1953 https://bugzilla.redhat.com/show_bug.cgi?id=1815212 • CWE-20: Improper Input Validation •
