The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday placed two security flaws impacting Microsoft Partner Center and Synacor Zimbra Collaboration Suite (ZCS) to its Known Exploited Vulnerabilities (KEV) catalog, based on evidence of active exploitation. The vulnerabilities in question are as follows - CVE-2024-49035 (CVSS score: 8.7) - An improper access control

Since joining the Common Vulnerabilities and Exposures (CVE) Program in 2002, Red Hat has been committed to excellence, growth and innovation in product security. Today, we’re pleased to announce that Red Hat is now a CVE Numbering Authority of Last Resort (CNA-LR), a prestigious recognition of our leadership, expertise and continued commitment to industry advancement. This achievement is a testament to Red Hat’s dedication and a significant success for the entire open source software (OSS) community of which we are proud to be a part.Red Hat’s role as a CNA remains, with the company bei

Cloud “container” defenses have inconsistencies that can give attackers too much access. A new company, Edera, is taking on that challenge and the problem of the male-dominated startup world.

### Impact The matrix-appservice-irc bridge up to version 3.0.3 contains a vulnerability which can lead to arbitrary IRC command execution as the puppeted user. The attacker can only inject commands executed as their own IRC user. ### Patches The vulnerability has been patched in matrix-appservice-irc version 3.0.4. ### For more information If you have any questions or comments about this advisory, please email us at [security at matrix.org](mailto:security@matrix.org).

> [!NOTE] > This advisory was originally emailed to community@solidjs.com by @nsysean. To sum it up, the use of javascript's `.replace()` opens up to potential XSS vulnerabilities with the special replacement patterns beginning with `$`. Particularly, when the attributes of `Meta` tag from solid-meta are user-defined, attackers can utilise the special replacement patterns, either `$'` or `$\`` to achieve XSS. The solid-meta package has this issue since it uses `useAffect` and context providers, which injects the used assets in the html header. "dom-expressions" uses `.replace()` to insert the assets, which is vulnerable to the special replacement patterns listed above. This effectively means that if the attributes of an asset tag contained user-controlled data, it would be vulnerable to XSS. For instance, there might be meta tags for the open graph protocol in a user profile page, but if attackers set the user query to some payload abusing `.replace()`, then they could execute a...

Inserts/JSX expressions inside illegal inlined JSX fragments lacked escaping, allowing user input to be rendered as HTML when put directly inside JSX fragments. For instance, `?text=<svg/onload=alert(1)>` would trigger XSS here. ```js const [text] = createResource(() => { return new URL(getRequestEvent().request.url).searchParams.get("text"); }); return ( <> Text: {text()} </> ); ```

### Summary In certain Subsonic API endpoints, authentication can be bypassed by using a non-existent username combined with an empty (salted) password hash. This allows read-only access to the server’s resources, though attempts at write operations fail with a “permission denied” error. ### Details A flaw in the authentication check process allows an attacker to specify any arbitrary username that does not exist on the system, along with a salted hash of an empty password. Under these conditions, Navidrome treats the request as authenticated, granting access to various Subsonic endpoints without requiring valid credentials. ### Proof of Concept (PoC) 1. Generate a random salt: ```javascript // e.g., salt = "x1vbudn1m6d" Math.random().toString(36).substring(2, 15) ``` 2. Calculate the MD5 hash of an empty password plus the salt: ```shell # Using the example salt above echo -n "x1vbudn1m6d" | md5sum 81f0c0fb5d202ab0d012e6eaeb722d79 - ``` 3. Send a re...

### Impact Only users that has configured a JupyterHub installation to use the authenticator class `LTI13Authenticator` are influenced. LTI13Authenticator that was introduced in `jupyterhub-ltiauthenticator` 1.3.0 wasn't validating JWT signatures. This is believed to allow the LTI13Authenticator to authorize a forged request granting access to existing and new user identities. ### Patches None. ### Workarounds None. ### References - [This code segment](https://github.com/jupyterhub/ltiauthenticator/blob/3feec2e81b9d3b0ad6b58ab4226af640833039f3/ltiauthenticator/lti13/validator.py#L122-L164) didn't validate a JWT signature.
