CVSS: 7.5EPSS: 0%CPEs: 55EXPL: 1CVE-2020-17527 – Apache Tomcat: Request header mix-up between HTTP/2 streams
https://notcve.org/view.php?id=CVE-2020-17527
While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to 9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak between requests. Al investigar el error 64830, se detectó que Apache Tomcat versiones 10.0.0-M1 hasta 10.0.0-M9, versiones 9.0.0-M1 hasta 9.0.39 y versiones 8.5.0 hasta 8.5.59, podría reutilizar un valor de encabezado de petición HTTP de la transmisión anterior recibida en una conexión HTTP/2 para la petición asociada con la transmisión posterior. Si bien esto probablemente conllevaría a un error y al cierre de la conexión HTTP/2, es posible que la información podría filtrarse entre peticiones • https://github.com/forse01/CVE-2020-17527-Tomcat http://www.openwall.com/lists/oss-security/2020/12/03/3 https://lists.apache.org/thread.html/r26a2a66339087fc37db3caf201e446d3e83b5cce314371e235ff1784%40%3Ccommits.tomee.apache.org%3E https://lists.apache.org/thread.html/r2d6e05c5ff96f8068a59dfdb3800e9ee8d4e36ce1971783c6e5f9b20%40%3Ccommits.tomee.apache.org%3E https://lists.apache.org/thread.html/r5a285242737ddef4d338236328aaaf3237183e1465a5efafd16b99ed%40%3Cdev.tomcat.apache.org%3E https://lists.apache.org/thread.html/r8a227ac6a755a6406c1cc47dd48800e973d4cf13fe7f • CWE-200: Exposure of Sensitive Information to an Unauthorized Actor •
CVSS: 8.7EPSS: 0%CPEs: 4EXPL: 0CVE-2020-26237 – Prototype Pollution in highlight.js
https://notcve.org/view.php?id=CVE-2020-26237
Highlight.js is a syntax highlighter written in JavaScript. Highlight.js versions before 9.18.2 and 10.1.2 are vulnerable to Prototype Pollution. A malicious HTML code block can be crafted that will result in prototype pollution of the base object's prototype during highlighting. If you allow users to insert custom HTML code blocks into your page/app via parsing Markdown code blocks (or similar) and do not filter the language names the user can provide you may be vulnerable. The pollution should just be harmless data but this can cause problems for applications not expecting these properties to exist and can result in strange behavior or application crashes, i.e. a potential DOS vector. • https://github.com/highlightjs/highlight.js/commit/7241013ae011a585983e176ddc0489a7a52f6bb0 https://github.com/highlightjs/highlight.js/pull/2636 https://github.com/highlightjs/highlight.js/security/advisories/GHSA-vfrc-7r7c-w9mx https://lists.debian.org/debian-lts-announce/2020/12/msg00041.html https://www.npmjs.com/package/highlight.js https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2020-26237 https://bugzilla.redhat.com/show_bug.cgi?id=1901662 • CWE-20: Improper Input Validation CWE-471: Modification of Assumed-Immutable Data (MAID) •

https://notcve.org/view.php?id=CVE-2019-0230
Apache Struts 2.0.0 to 2.5.20 forced double OGNL evaluation, when evaluated on raw user input in tag attributes, may lead to remote code execution. Apache Struts versiones 2.0.0 hasta 2.5.20, forzó una evaluación OGNL doble, cuando se evaluaba en la entrada del usuario sin procesar en los atributos de la etiqueta, puede conllevar a una ejecución de código remota The Apache Struts framework, when forced, performs double evaluation of attribute values assigned to certain tags attributes such as id. It is therefore possible to pass in a value to Struts that will be evaluated again when a tag's attributes are rendered. With a carefully crafted request, this can lead to remote code execution. This vulnerability is application dependant. • https://www.exploit-db.com/exploits/49068 https://github.com/PrinceFPF/CVE-2019-0230 https://github.com/BH2UOL/CVE-2019-0230 https://github.com/ramoncjs3/CVE-2019-0230 https://github.com/Al1ex/CVE-2019-0230 https://github.com/fengziHK/CVE-2019-0230 https://github.com/f8al/CVE-2019-0230-PoC http://packetstormsecurity.com/files/160108/Apache-Struts-2.5.20-Double-OGNL-Evaluation.html http://packetstormsecurity.com/files/160721/Apache-Struts-2-Forced-Multi-OGNL-Evaluation.html http • CWE-1321: Improperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution') •
