Zabbix Agent and Zabbix Agent 2 versions 6.2.7 and below suffer from an issue where it does not secure the permissions on a non-default installation directory, allowing an attacker to place a malicious executable to escalate privileges.

The Raccoon attack is a timing attack on DHE ciphersuites inherit in the TLS specification. To mitigate this vulnerability, Firefox disabled support for DHE ciphersuites.

A path traversal vulnerability was identified in GitHub Enterprise Server that allowed arbitrary file reading when building a GitHub Pages site. To exploit this vulnerability, an attacker would need permission to create and build a GitHub Pages site on the GitHub Enterprise Server instance. This vulnerability affected all versions of GitHub Enterprise Server since 3.7 and was fixed in version 3.7.6. This vulnerability was reported via the GitHub Bug Bounty program.

### Impact All Argo CD versions starting with v2.3.0-rc1 are vulnerable to an improper authorization bug which allows users who have the ability to update at least one cluster secret to update any cluster secret. The attacker could use this access to escalate privileges (potentially controlling Kubernetes resources) or to break Argo CD functionality (by preventing connections to external clusters). #### How the Attack Works Argo CD stores [cluster access configurations](https://argo-cd.readthedocs.io/en/stable/operator-manual/declarative-setup/#clusters) as Kubernetes Secrets. To take advantage of the vulnerability, an attacker must know the server URL for the cluster secret they want to modify. The attacker must be authenticated with the Argo CD API server, and they must be authorized to update at least one ([non project-scoped](https://argo-cd.readthedocs.io/en/stable/user-guide/projects/#project-scoped-repositories-and-clusters)) cluster. Then they must craft a malicious reque...

It was discovered that the sls-logging was not verifying hostnames in TLS certificates due to a misuse of the javax.net.ssl.SSLSocketFactory API. A malicious attacker in a privileged network position could abuse this to perform a man-in-the-middle attack. A successful man-in-the-middle attack would allow them to intercept, read, or modify network communications to and from the affected service. In the case of AtlasDB, the vulnerability was mitigated by other network controls such as two-way TLS when deployed as part of a Palantir platform. Palantir still recommends upgrading to a non-vulnerable version out of an abundance of caution.

It was discovered that the Magritte-ftp was not verifying hostnames in TLS certificates due to a misuse of the javax.net.ssl.SSLSocketFactory API. A malicious attacker in a privileged network position could abuse this to perform a man-in-the-middle attack. A successful man-in-the-middle attack would allow them to intercept, read, or modify network communications to and from the affected service. In the case of a successful man in the middle attack on magritte-ftp, an attacker would be able to read and modify network traffic such as authentication tokens or raw data entering a Palantir Foundry stack.

Improper Validation of Certificate with Host Mismatch vulnerability in Gotham Chat IRC helper of Palantir Gotham allows A malicious attacker in a privileged network position could abuse this to perform a man-in-the-middle attack. A successful man-in-the-middle attack would allow them to intercept, read, or modify network communications to and from the affected service. This issue affects: Palantir Palantir Gotham Chat IRC helper versions prior to 30221005.210011.9242.
