https://notcve.org/view.php?id=CVE-2021-25329
The fix for CVE-2020-9484 was incomplete. When using Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41, 8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 with a configuration edge case that was highly unlikely to be used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to this issue.

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. •
CVSS: 5.9EPSS: 0%CPEs: 38EXPL: 0CVE-2021-23841 – Null pointer deref in X509_issuer_and_serial_hash()
https://notcve.org/view.php?id=CVE-2021-23841
The OpenSSL public API function X509_issuer_and_serial_hash() attempts to create a unique hash value based on the issuer and serial number data contained within an X509 certificate. However it fails to correctly handle any errors that may occur while parsing the issuer field (which might occur if the issuer field is maliciously constructed). This may subsequently result in a NULL pointer deref and a crash leading to a potential denial of service attack. The function X509_issuer_and_serial_hash() is never directly called by OpenSSL itself so applications are only vulnerable if they use this function directly and they use it on certificates that may have been obtained from untrusted sources. OpenSSL versions 1.1.1i and below are affected by this issue. • http://seclists.org/fulldisclosure/2021/May/67 http://seclists.org/fulldisclosure/2021/May/68 http://seclists.org/fulldisclosure/2021/May/70 https://cert-portal.siemens.com/productcert/pdf/ssa-637483.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=122a19ab48091c657f7cb1fb3af9fc07bd557bbf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=8252ee4d90f3f2004d3d0aeeed003ad49c9a7807 https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44846 https://security.gentoo.org/gls • CWE-476: NULL Pointer Dereference •

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') •
