CVSS: 9.8EPSS: 0%CPEs: 8EXPL: 2CVE-2021-29921 – python-ipaddress: Improper input validation of octal strings
https://notcve.org/view.php?id=CVE-2021-29921
In Python before 3,9,5, the ipaddress library mishandles leading zero characters in the octets of an IP address string. This (in some situations) allows attackers to bypass access control that is based on IP addresses. En Python antes de la versiones 3,9,5, la biblioteca ipaddress maneja mal los caracteres cero iniciales en los octetos de una cadena de direcciones IP. Esto (en algunas situaciones) permite a los atacantes eludir el control de acceso que se basa en las direcciones IP A flaw was found in python-ipaddress. Improper input validation of octal strings in stdlib ipaddress allows unauthenticated remote attackers to perform indeterminate SSRF, RFI, and LFI attacks on many programs that rely on Python stdlib ipaddress. • https://bugs.python.org/issue36384 https://docs.python.org/3/library/ipaddress.html https://github.com/python/cpython/blob/63298930fb531ba2bb4f23bc3b915dbf1e17e9e1/Misc/NEWS.d/3.8.0a4.rst https://github.com/python/cpython/pull/12577 https://github.com/python/cpython/pull/25099 https://github.com/sickcodes https://github.com/sickcodes/security/blob/master/advisories/SICK-2021-014.md https://python-security.readthedocs.io/vuln/ipaddress-ipv4-leading-zeros.html https://security.gentoo.org/gl • CWE-20: Improper Input Validation •

CVSS: 7.4EPSS: 0%CPEs: 56EXPL: 0CVE-2021-3450 – CA certificate check bypass with X509_V_FLAG_X509_STRICT
https://notcve.org/view.php?id=CVE-2021-3450
The X509_V_FLAG_X509_STRICT flag enables additional security checks of the certificates present in a certificate chain. It is not set by default. Starting from OpenSSL version 1.1.1h a check to disallow certificates in the chain that have explicitly encoded elliptic curve parameters was added as an additional strict check. An error in the implementation of this check meant that the result of a previous check to confirm that certificates in the chain are valid CA certificates was overwritten. This effectively bypasses the check that non-CA certificates must not be able to issue other certificates. • http://www.openwall.com/lists/oss-security/2021/03/27/1 http://www.openwall.com/lists/oss-security/2021/03/27/2 http://www.openwall.com/lists/oss-security/2021/03/28/3 http://www.openwall.com/lists/oss-security/2021/03/28/4 https://cert-portal.siemens.com/productcert/pdf/ssa-389290.pdf https://git.openssl.org/gitweb/?p=openssl.git%3Ba=commitdiff%3Bh=2a40b7bc7b94dd7de897a74571e7024f0cf0d63b https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA44845 https://kc.mc • CWE-295: Improper Certificate Validation •
