CVSS: 7.5EPSS: 0%CPEs: 8EXPL: 1CVE-2021-26296 – Cross-Site Request Forgery (CSRF) vulnerability in Apache MyFaces
https://notcve.org/view.php?id=CVE-2021-26296
In the default configuration, Apache MyFaces Core versions 2.2.0 to 2.2.13, 2.3.0 to 2.3.7, 2.3-next-M1 to 2.3-next-M4, and 3.0.0-RC1 use cryptographically weak implicit and explicit cross-site request forgery (CSRF) tokens. Due to that limitation, it is possible (although difficult) for an attacker to calculate a future CSRF token value and to use that value to trick a user into executing unwanted actions on an application. En la configuración predeterminada, Apache MyFaces Core versiones 2.2.0 hasta 2.2.13, versiones 2.3.0 hasta 2.3.7, versiones 2.3-next-M1 hasta 2.3-next-M4 y 3.0.0-RC1, usan tokens de tipo cross-site request forgery (CSRF) implícitos y explícitos criptográficamente débiles. Debido a esa limitación, es posible (aunque difícil) para un atacante calcular un valor futuro de token CSRF y usar ese valor para engañar al usuario a ejecutar acciones no deseadas en una aplicación Apache MyFaces versions 2.2.13 and below, 2.3.7 and below, 2.3-next-M4 and below, and 2.1 and below suffer from a cross site request forgery vulnerability. • http://packetstormsecurity.com/files/161484/Apache-MyFaces-2.x-Cross-Site-Request-Forgery.html http://seclists.org/fulldisclosure/2021/Feb/66 https://lists.apache.org/thread.html/r2b73e2356c6155e9ec78fdd8f72a4fac12f3e588014f5f535106ed9b%40%3Cannounce.apache.org%3E https://security.netapp.com/advisory/ntap-20210528-0007 • CWE-352: Cross-Site Request Forgery (CSRF) •
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 •
