CVE-2022-23500 – TYPO3 subject to Uncontrolled Recursion resulting in Denial of Service
https://notcve.org/view.php?id=CVE-2022-23500
TYPO3 is an open source PHP based web content management system. In versions prior to 9.5.38, 10.4.33, 11.5.20, and 12.1.1, requesting invalid or non-existing resources via HTTP triggers the page error handler, which again could retrieve content to be shown as an error message from another page. This leads to a scenario in which the application is calling itself recursively - amplifying the impact of the initial attack until the limits of the web server are exceeded. This vulnerability is very similar, but not identical, to the one described in CVE-2021-21359. This issue is patched in versions 9.5.38 ELTS, 10.4.33, 11.5.20 or 12.1.1. • https://github.com/TYPO3/typo3/security/advisories/GHSA-8c28-5mp7-v24h • CWE-674: Uncontrolled Recursion •
CVE-2022-23499 – Cross-Site Scripting Protection bypass in HTML Sanitizer
https://notcve.org/view.php?id=CVE-2022-23499
HTML sanitizer is written in PHP, aiming to provide XSS-safe markup based on explicitly allowed tags, attributes and values. In versions prior to 1.5.0 or 2.1.1, malicious markup used in a sequence with special HTML CDATA sections cannot be filtered and sanitized due to a parsing issue in the upstream package masterminds/html5. This allows bypassing the cross-site scripting mechanism of typo3/html-sanitizer. The upstream package masterminds/html5 provides HTML raw text elements (`script`, `style`, `noframes`, `noembed` and `iframe`) as DOMText nodes, which were not processed and sanitized further. None of the mentioned elements were defined in the default builder configuration, that's why only custom behaviors, using one of those tag names, were vulnerable to cross-site scripting. • https://github.com/TYPO3/html-sanitizer/security/advisories/GHSA-hvwx-qh2h-xcfj • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
CVE-2022-36105 – User Enumeration via Response Timing in TYPO3
https://notcve.org/view.php?id=CVE-2022-36105
TYPO3 is an open source PHP based web content management system released under the GNU GPL. It has been discovered that observing response time during user authentication (backend and frontend) can be used to distinguish between existing and non-existing user accounts. Extension authors of 3rd party TYPO3 extensions providing a custom authentication service should check if the extension is affected by the described problem. Affected extensions must implement new `MimicServiceInterface::mimicAuthUser`, which simulates corresponding times regular processing would usually take. Update to TYPO3 version 7.6.58 ELTS, 8.7.48 ELTS, 9.5.37 ELTS, 10.4.32 or 11.5.16 that fix this problem. • https://github.com/TYPO3/typo3/commit/f8b83ce15d4ea275a5a5e564e5d324242f7937b6 https://github.com/TYPO3/typo3/security/advisories/GHSA-m392-235j-9r7r https://typo3.org/security/advisory/typo3-core-sa-2022-007 • CWE-203: Observable Discrepancy •
CVE-2022-36106 – Missing check for expiration time of password reset token in TYPO3
https://notcve.org/view.php?id=CVE-2022-36106
TYPO3 is an open source PHP based web content management system released under the GNU GPL. It has been discovered that the expiration time of a password reset link for TYPO3 backend users has never been evaluated. As a result, a password reset link could be used to perform a password reset even if the default expiry time of two hours has been exceeded. Update to TYPO3 version 10.4.32 or 11.5.16 that fix the problem. There are no known workarounds for this issue. • https://github.com/TYPO3/typo3/commit/56af2bd3a432156c30af9be71c9d6f7ef3a6159a https://github.com/TYPO3/typo3/security/advisories/GHSA-5959-4x58-r8c2 https://typo3.org/security/advisory/typo3-core-sa-2022-008 • CWE-287: Improper Authentication •
CVE-2022-36107 – Stored Cross-Site Scripting via FileDumpController
https://notcve.org/view.php?id=CVE-2022-36107
TYPO3 is an open source PHP based web content management system released under the GNU GPL. It has been discovered that the `FileDumpController` (backend and frontend context) is vulnerable to cross-site scripting when malicious files are displayed using this component. A valid backend user account is needed to exploit this vulnerability. Update to TYPO3 version 7.6.58 ELTS, 8.7.48 ELTS, 9.5.37 ELTS, 10.4.32 or 11.5.16 that fix the problem. There are no known workarounds for this issue. • https://github.com/TYPO3/typo3/commit/bd58d2ff2eeef89e63ef754a2389597d22622a39 https://github.com/TYPO3/typo3/security/advisories/GHSA-9c6w-55cp-5w25 https://typo3.org/security/advisory/typo3-core-sa-2022-009 • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
