Incorrect Default Permissions vulnerability in Apache Tomcat Connectors allows local users to view and modify shared memory containing mod_jk configuration which may lead to information disclosure and/or denial of service. This issue affects Apache Tomcat Connectors: from 1.2.9-beta through 1.2.49. Only mod_jk on Unix like systems is affected. Neither the ISAPI redirector nor mod_jk on Windows is affected.

    Package        : libapache-mod-jk     Version        : 1:1.2.48-1+deb11u2     CVE ID         : CVE-2024-46544     Debian Bug     : 1082713

    It was discovered that there was a configuration issue in     libapache-mod-jk, an Apache web server module used to forward     requests from Apache to Tomcat using the AJP protocol.

    An issue with incorrect default permissions could have allowed local     users to view and modify shared memory containing mod_jk's     configuration, which may have potentially led to information     disclosure and/or a denial of service attack.

    For Debian 11 bullseye, this problem has been fixed in version     1:1.2.48-1+deb11u2.

    We recommend that you upgrade your libapache-mod-jk packages.

    For the detailed security status of libapache-mod-jk please refer to     its security tracker page at:
