Microsoft's September 2024 Patch Tuesday is here. Make sure you’ve applied the necessary patches!

Microsoft Corp. today released updates to fix at least 79 security vulnerabilities in its Windows operating systems and related software, including multiple flaws that are already showing up in active attacks. Microsoft also corrected a critical bug that has caused some Windows 10 PCs to remain dangerously unpatched against actively exploited vulnerabilities for several months this year.

This month's Patch Tuesday contains a total of 79 vulnerabilities — the fourth largest of the year.

In this case study, a 180-year-old life and pension insurer brought its security infrastructure into the modern age.

### Summary Unauthenticated user can access credentials of last authenticated user via OpenID or OAuth2 where the authentication URL did not include `redirect` query string. For example: - Project is configured with OpenID or OAuth2 - Project is configured with cache enabled - User tries to login via SSO link, but without `redirect` query string - After successful login, credentials are cached - If an unauthenticated user tries to login via SSO link, it will return the credentials of the other last user The SSO link is something like `https://directus.example.com/auth/login/openid/callback`, where `openid` is the name of the OpenID provider configured in Directus ### Details This happens because on that endpoint for both OpenId and Oauth2 Directus is using the `respond` middleware, which by default will try to cache GET requests that met some conditions. Although, those conditions do not include this scenario, when an unauthenticated request returns user credentials. For OpenID, thi...

### Impact Users hosting D-Tale publicly can be vulnerable to remote code execution allowing attackers to run malicious code on the server. ### Patches Users should upgrade to version 3.14.1 where the "Custom Filter" input is turned off by default. You can find out more information on how to turn it back on [here](https://github.com/man-group/dtale#custom-filter) ### Workarounds The only workaround for versions earlier than 3.14.1 is to only host D-Tale to trusted users. ### References See "Custom Filter" [documentation](https://github.com/man-group/dtale#custom-filter)

### Impact passing untrusted user input - even after sanitizing it - to `redirect()` may execute untrusted code ### Patches this issue is patched in serve-static 1.16.0 ### Workarounds users are encouraged to upgrade to the patched version of express, but otherwise can workaround this issue by making sure any untrusted inputs are safe, ideally by validating them against an explicit allowlist ### Details successful exploitation of this vector requires the following: 1. The attacker MUST control the input to response.redirect() 1. express MUST NOT redirect before the template appears 1. the browser MUST NOT complete redirection before: 1. the user MUST click on the link in the template

### Impact In express <4.20.0, passing untrusted user input - even after sanitizing it - to `response.redirect()` may execute untrusted code ### Patches this issue is patched in express 4.20.0 ### Workarounds users are encouraged to upgrade to the patched version of express, but otherwise can workaround this issue by making sure any untrusted inputs are safe, ideally by validating them against an explicit allowlist ### Details successful exploitation of this vector requires the following: 1. The attacker MUST control the input to response.redirect() 1. express MUST NOT redirect before the template appears 1. the browser MUST NOT complete redirection before: 1. the user MUST click on the link in the template

Besides operational issues connected to a talent shortage, the cost of running security platforms — and their training costs — also keeps CISOs up at night.
