### Description An ExecSync request runs a command in a container and returns the output to the Kubelet. It is used for readiness and liveness probes within a pod. The way CRI-O runs ExecSync commands is through conmon. CRI-O asks conmon to start the process, and conmon writes the output to disk. CRI-O then reads the output and returns it to the Kubelet. If the output of the command is large enough, it is possible to exhaust the memory (or disk usage) of the node. The following deployment is an example yaml file that will output around 8GB of ‘A’ characters, which would be written to disk by conmon and read by CRI-O. ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: nginx-deployment100 spec: selector: matchLabels: app: nginx replicas: 2 template: metadata: labels: app: nginx spec: containers: - name: nginx image: nginx:1.14.2 lifecycle: postStart: exec: command: ["/bin/s...

Reolink E1 Zoom Camera versions 3.0.0.716 and below suffer from a configuration disclosure vulnerability.

IIPImage is distributed with a server that enables advanced, high-performance image manipulation for web-based streaming and viewing of high resolution images. The server component called iipsrv.fcgi processes requests from users and passes them to command handlers. Several crashes including an integer overflow were discovered by sending malformed requests to the server, allowing remote users without authentication to perform denial-of-service attacks or potentially crafted for remote code execution as the server's running user. Versions at least up to 1.1 may be affected.

BigBlueButton is an open source web conferencing system. Versions starting with 2.2 and prior to 2.3.19, 2.4.7, and 2.5.0-beta.2 are vulnerable to regular expression denial of service (ReDoS) attacks. By using specific a RegularExpression, an attacker can cause denial of service for the bbb-html5 service. The useragent library performs checking of device by parsing the input of User-Agent header and lets it go through lookupUserAgent() (alias of useragent.lookup() ). This function handles input by regexing and attackers can abuse that by providing some ReDos payload using `SmartWatch`. The maintainers removed `htmlclient/useragent` from versions 2.3.19, 2.4.7, and 2.5.0-beta.2. As a workaround, disable NginX forwarding the requests to the handler according to the directions in the GitHub Security Advisory.

Schneider Electric C-Bus Automation Controller (5500SHAC) version 1.10 suffers from an authenticated arbitrary command execution vulnerability. An attacker can abuse the Start-up (init) script editor and exploit the script POST parameter to insert malicious Lua script code and execute commands with root privileges that will grant full control of the device.

The automation controller suffers from an authenticated arbitrary command execution vulnerability. An attacker can abuse the Start-up (init) script editor and exploit the 'script' POST parameter to insert malicious Lua script code and execute commands with root privileges that will grant full control of the device.
