CVE-2021-22112
https://notcve.org/view.php?id=CVE-2021-22112
Spring Security 5.4.x prior to 5.4.4, 5.3.x prior to 5.3.8.RELEASE, 5.2.x prior to 5.2.9.RELEASE, and older unsupported versions can fail to save the SecurityContext if it is changed more than once in a single request.A malicious user cannot cause the bug to happen (it must be programmed in). However, if the application's intent is to only allow the user to run with elevated privileges in a small portion of the application, the bug can be leveraged to extend those privileges to the rest of the application. Spring Security versiones 5.4.x anteriores a 5.4.4, versiones 5.3.x anteriores a 5.3.8.RELEASE, versiones 5.2.x anteriores a 5.2.9.RELEASE, y versiones anteriores no compatibles, pueden producir un fallo al guardar el SecurityContext si se cambia más de una vez en una sola petición. Un usuario malicioso no puede causar el error (debe estar programado). Sin embargo, si la intención de la aplicación es sólo permitir que el usuario solo se ejecute con privilegios elevados en una pequeña parte de la aplicación, el error puede ser aprovechado para extender esos privilegios al resto de la aplicación • http://www.openwall.com/lists/oss-security/2021/02/19/7 https://lists.apache.org/thread.html/r163b3e4e39803882f5be05ee8606b2b9812920e196daa2a82997ce14%40%3Cpluto-dev.portals.apache.org%3E https://lists.apache.org/thread.html/r2cb05e499807900ba23e539643eead9c5f0652fd271f223f89da1804%40%3Cpluto-scm.portals.apache.org%3E https://lists.apache.org/thread.html/r37423ec7eea340e92a409452c35b649dce02fdc467f0b3f52086c177%40%3Cpluto-dev.portals.apache.org%3E https://lists.apache.org/thread.html/r3868207b967f926819fe3aa8d33f1666429be589bb4a62104a49f4e3%40%3Cpluto-dev.portals.apache. •
CVE-2020-17530 – Apache Struts Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2020-17530
Forced OGNL evaluation, when evaluated on raw user input in tag attributes, may lead to remote code execution. Affected software : Apache Struts 2.0.0 - Struts 2.5.25. Una evaluación OGNL forzada, cuando se evalúa según la entrada del usuario sin procesar en los atributos de la etiqueta, puede conllevar a una ejecución de código remota. Software afectado: Apache Struts versión 2.0.0 - Struts versión 2.5.25 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. • https://github.com/wuzuowei/CVE-2020-17530 https://github.com/ka1n4t/CVE-2020-17530 https://github.com/Al1ex/CVE-2020-17530 https://github.com/phil-fly/CVE-2020-17530 https://github.com/CyborgSecurity/CVE-2020-17530 https://github.com/fengziHK/CVE-2020-17530-strust2-061 https://github.com/uzzzval/CVE-2020-17530 https://github.com/nth347/CVE-2020-17530 https://github.com/secpool2000/CVE-2020-17530 https://github.com/keyuan15/CVE-2020-17530 https://github.com/kil • CWE-917: Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection') •
CVE-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) •
