#ssh

Sourcegraph is a code search and navigation engine. Sourcegraph prior to version 3.37 is vulnerable to remote code execution in the `gitserver` service. The service acts as a git exec proxy, and fails to properly restrict calling `git config`. This allows an attacker to set the git `core.sshCommand` option, which sets git to use the specified command instead of ssh when they need to connect to a remote system. Exploitation of this vulnerability depends on how Sourcegraph is deployed. An attacker able to make HTTP requests to internal services like gitserver is able to exploit it. This issue is patched in Sourcegraph version 3.37. As a workaround, ensure that requests to gitserver are properly protected.

A flaw was found in mbsync before v1.3.6 and v1.4.2, where an unchecked pointer cast allows a malicious or compromised server to write an arbitrary integer value past the end of a heap-allocated structure by issuing an unexpected APPENDUID response. This could be plausibly exploited for remote code execution on the client.

Missing permission checks in Jenkins Checkmarx Plugin 2022.1.2 and earlier allow attackers with Overall/Read permission to connect to an attacker-specified webserver using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

A cross-site request forgery (CSRF) vulnerability in Jenkins SCP publisher Plugin 1.8 and earlier allows attackers to connect to an attacker-specified SSH server using attacker-specified credentials.

Jenkins Fortify Plugin 20.2.34 and earlier does not sanitize the appName and appVersion parameters of its Pipeline steps, allowing attackers with Item/Configure permission to write or overwrite .xml files on the Jenkins controller file system with content not controllable by the attacker.

A sandbox bypass vulnerability in Jenkins Pipeline: Shared Groovy Libraries Plugin 552.vd9cc05b8a2e1 and earlier allows attackers with Item/Configure permission to execute arbitrary code in the context of the Jenkins controller JVM through crafted SCM contents, if a global Pipeline library already exists.

Jenkins HashiCorp Vault Plugin 3.8.0 and earlier implements functionality that allows agent processes to retrieve any Vault secrets for use on the agent, allowing attackers able to control agent processes to obtain Vault secrets for an attacker-specified path and key.

Jenkins GitLab Authentication Plugin 1.13 and earlier records the HTTP Referer header as part of the URL query parameters when the authentication process starts, allowing attackers with access to Jenkins to craft a URL that will redirect users to an attacker-specified URL after logging in.

Missing permission checks in Jenkins Snow Commander Plugin 1.10 and earlier allow attackers with Overall/Read permission to connect to an attacker-specified webserver using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

Jenkins Promoted Builds (Simple) Plugin 1.9 and earlier does not escape the name of custom promotion levels, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Overall/Administer permission.
