A vulnerability was found in Tenda AC23 16.03.07.45 and classified as critical. Affected by this issue is the function formSetSysToolDDNS/formGetSysToolDDNS of the file /bin/httpd. The manipulation leads to stack-based buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used. The identifier of this vulnerability is VDB-220640.

Wyse Management Suite 3.8 and below contain an improper access control vulnerability. A authenticated malicious admin user can edit general client policy for which the user is not authorized.

DataHub is an open-source metadata platform. In the event a system is using Java Authentication and Authorization Service (JAAS) authentication and that system is given a configuration which contains an error, the authentication for the system will fail open and allow an attacker to login using any username and password. The reason for this is that while an error is thrown in the `authenticateJaasUser` method it is swallowed without propagating the error. As a result of this issue unauthenticated users may gain access to the system. Users are advised to upgrade. There are no known workarounds for this issue. This vulnerability was discovered and reported by the GitHub Security lab and is tracked as GHSL-2022-081.

DataHub is an open-source metadata platform. When the DataHub frontend is configured to authenticate via SSO, it will leverage the pac4j library. The processing of the `id_token` is done in an unsafe manner which is not properly accounted for by the DataHub frontend. Specifically, if any of the id_token claims value start with the {#sb64} prefix, pac4j considers the value to be a serialized Java object and will deserialize it. This issue may lead to Remote Code Execution (RCE) in the worst case. Although a `RestrictedObjectInputStream` is in place, that puts some restriction on what classes can be deserialized, it still allows a broad range of java packages and potentially exploitable with different gadget chains. Users are advised to upgrade. There are no known workarounds. This vulnerability was discovered and reported by the GitHub Security lab and is tracked as GHSL-2022-086.

DataHub is an open-source metadata platform. The DataHub frontend acts as a proxy able to forward any REST or GraphQL requests to the backend. The goal of this proxy is to perform authentication if needed and forward HTTP requests to the DataHub Metadata Store (GMS). It has been discovered that the proxy does not adequately construct the URL when forwarding data to GMS, allowing external users to reroute requests from the DataHub Frontend to any arbitrary hosts. As a result attackers may be able to reroute a request from originating from the frontend proxy to any other server and return the result. This vulnerability was discovered and reported by the GitHub Security lab and is tracked as GHSL-2022-076.

### Summary Because of the missing `checkLink(String)` override in the SecurityManager, students can load libraries and execute arbitrary code. ### Details Using `System.load(String)` or `System.loadLibrary​(String)` students can load and execute arbitrary code. ```java private static native void start(List<String> args); public static void main(String[] args) { System.load(new File("path_to_lib.so").getAbsolutePath()); start(List.of(args)); } ``` Adding this to the security manager (and a translation) should fix the issue: ```java @Override public void checkExec(String cmd) { try { if (enterPublicInterface()) return; throw new SecurityException(localized("security.error_link")); //$NON-NLS-1$ } finally { exitPublicInterface(); } } ``` ### PoC See details. ### Impact Arbitrary code execution.

Valve's unpatched JavaScript engine and incomplete modification vetting process for Steam-delivered mods led to user systems being backdoored.

Four different rogue packages in the Python Package Index (PyPI) have been found to carry out a number of malicious actions, including dropping malware, deleting the netstat utility, and manipulating the SSH authorized_keys file. The packages in question are aptx, bingchilling2, httops, and tkint3rs, all of which were collectively downloaded about 450 times before they were taken down. While
