The py library through 1.11.0 for Python allows remote attackers to conduct a ReDoS (Regular expression Denial of Service) attack via a Subversion repository with crafted info data, because the InfoSvnCommand argument is mishandled.

### Impact If a gateway client application sends a malformed request to a gateway peer it may crash the peer node. This fix checks for the malformed gateway request and returns an error to the gateway client. ### Patches Fixed in v2.4.6. ### Workarounds None, users must upgrade to v2.4.6. ### References https://github.com/hyperledger/fabric/releases/tag/v2.4.6 ### For more information If you have any questions or comments about this advisory: * Open an issue in [Fabric](https://github.com/hyperledger/fabric) ### Credits Thank you to Haosheng Wang of OPPO ZIWU Security Lab for this disclosure.

### Impact This vulnerability only affects installations that rely on the safe mode restriction, commonly used when providing public access to the admin panel. Assuming an attacker has access to the admin panel and permission to open the "Editor" section, they can bypass the Safe Mode (`cms.safe_mode`) restriction to introduce new PHP code in a CMS template using a specially crafted request. ### Patches The issue has been patched in v2.2.34 and v3.0.66 ### References Credits to: - David Miller ### For more information If you have any questions or comments about this advisory: - Email us at [[email protected]](mailto:[email protected])

Apache Commons Text performs variable interpolation, allowing properties to be dynamically evaluated and expanded. The standard format for interpolation is "${prefix:name}", where "prefix" is used to locate an instance of org.apache.commons.text.lookup.StringLookup that performs the interpolation. Starting with version 1.5 and continuing through 1.9, the set of default Lookup instances included interpolators that could result in arbitrary code execution or contact with remote servers. These lookups are: - "script" - execute expressions using the JVM script execution engine (javax.script) - "dns" - resolve dns records - "url" - load values from urls, including from remote servers Applications using the interpolation defaults in the affected versions may be vulnerable to remote code execution or unintentional contact with remote servers if untrusted configuration values are used. Users are recommended to upgrade to Apache Commons Text 1.10.0, which disables the problematic interpolators ...

powerline-gitstatus (aka Powerline Gitstatus) before 1.3.2 allows arbitrary code execution. git repositories can contain per-repository configuration that changes the behavior of git, including running arbitrary commands. When using powerline-gitstatus, changing to a directory automatically runs git commands in order to display information about the current repository in the prompt. If an attacker can convince a user to change their current directory to one controlled by the attacker, such as in a shared filesystem or extracted archive, powerline-gitstatus will run arbitrary commands under the attacker's control. NOTE: this is similar to CVE-2022-20001.

### Impact A remote attacker may be able to bypass SAML authentication on a website using passport-saml. A successful attack requires that the attacker is in possession of an arbitrary IDP signed XML element. Depending on the IDP used, fully unauthenticated attacks (e.g without access to a valid user) might also be feasible if generation of a signed message can be triggered. ### Patches Users should upgrade to node-saml v4.0.0-beta5 or newer. ### Workarounds Disable SAML authentication. ### References _Are there any links users can visit to find out more?_ ### For more information If you have any questions or comments about this advisory: * Open a discussion in the [node-saml repo](https://github.com/node-saml/node-saml/discussions) ### Credits * Felix Wilhelm of Google Project Zero
