![]() In Festo Controller CECC-X-M1 product family in multiple versions, the http-endpoint "cecc-x-web-viewer-request-on" POST request doesn’t check for port syntax. This can result in unauthorized execution of system commands with root privileges due to improper access control command injection. In Festo Controller CECC-X-M1 product family in multiple versions, the http-endpoint "cecc-x-web-viewer-request-off" POST request doesn’t check for port syntax. In Festo Controller CECC-X-M1 product family in multiple versions, the http-endpoint "cecc-x-acknerr-request" POST request doesn’t check for port syntax. In Festo Controller CECC-X-M1 product family in multiple versions, the http-endpoint "cecc-x-refresh-request" POST request doesn’t check for port syntax. ![]() The attackers can exploit the vulnerability to carry out arbitrary code by means of sending a specially constructed payload to port 49152. The function created at 0x17958 of /htdocs/cgibin will call sprintf without checking the length of strings in parameters given by HTTP header and can be controlled by users easily. The LAN-side Web-Configuration Interface has Stack-based Buffer Overflow vulnerability in the D-Link Wi-Fi router firmware DIR-890L DIR890LA1_FW107b09.bin and previous versions. There are no known workarounds for this issue. Users are advised to upgrade to Mechanize v2.8.5 or later. In versions prior to 2.8.5 the Authorization header is leaked after a redirect to a different port on the same site. Mechanize automatically stores and sends cookies, follows redirects, and can follow links and submit forms. The Mechanize library is used for automating interaction with websites. As a workaround, those who want to test challenges privately can mark them as `public: false` and use `kctf chal debug port-forward` to connect. Prior to version 1.6.0, the kctf cluster set-src-ip-ranges was broken and allowed traffic from any IP. ![]() KCTF is a Kubernetes-based infrastructure for capture the flag (CTF) competitions. See Configure universal forwarder management security () for more information on disabling the remote management services. If management services are not required in versions before 9.0, set disableDefaultPort = true in nf OR allowRemoteLogin = never in nf OR mgmtHostPort = localhost in web.conf. In 9.0, the universal forwarder now binds the management port to localhost preventing remote logins by default. If exposed, we recommend each customer assess the potential severity specific to your environment. When not required, it introduces a potential exposure, but it is not a vulnerability. In universal forwarder versions before 9.0, management services are available remotely by default. The Linux kernel before 5.17.9 allows TCP servers to identify clients by observing what source ports are used.
