exec.CommandContext in Chaosblade 0.3 through 1.7.3, when server mode is used, allows OS command execution via the cmd parameter without authentication.

Ubuntu Security Notice 6885-3 - USN-6885-1 fixed several vulnerabilities in Apache. This update provides the corresponding update for Ubuntu 16.04 LTS and Ubuntu 18.04 LTS. Orange Tsai discovered that the Apache HTTP Server mod_rewrite module incorrectly handled certain substitutions. A remote attacker could possibly use this issue to execute scripts in directories not directly reachable by any URL, or cause a denial of service. Some environments may require using the new UnsafeAllow3F flag to handle unsafe substitutions.

Ubuntu Security Notice 7021-1 - Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Ubuntu Security Notice 7020-1 - Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system.

Online Traffic Offense version 1.0 suffers from cross site request forgery and arbitrary file upload vulnerabilities.

A vulnerability has been discovered and fixed in Mesop that could potentially allow unauthorized access to files on the server hosting the Mesop application. The vulnerability was related to insufficient input validation in a specific endpoint. This could have allowed an attacker to access files not intended to be served. Users are strongly advised to update to the latest version of Mesop immediately. The latest version includes a fix for this vulnerability. We would like to thank @Letm3through for reporting this issue and proposing mitigations to address this issue.

### Impact If you're relying on blocking access to localhost using the default `0.0.0.0` filter this can be bypassed using other registered loopback devices (like `127.0.0.2` - `127.127.127.127`) ### Workaround You can block this bypass by manually adding the `127.0.0.0/8` CIDR range which will block access to any `127.X.X.X` ip instead of just `127.0.0.1`.
