CVSS: 9.0EPSS: 1%CPEs: 12EXPL: 2CVE-2021-45960 – expat: Large number of prefixed XML attributes on a single tag can crash libexpat
https://notcve.org/view.php?id=CVE-2021-45960
In Expat (aka libexpat) before 2.4.3, a left shift by 29 (or more) places in the storeAtts function in xmlparse.c can lead to realloc misbehavior (e.g., allocating too few bytes, or only freeing memory). En Expat (también se conoce como libexpat) versiones anteriores a 2.4.3, un desplazamiento a la izquierda por 29 (o más) lugares en la función storeAtts en el archivo xmlparse.c puede conllevar a un comportamiento incorrecto de reasignación (por ejemplo, asignar muy pocos bytes, o sólo liberar memoria). expat (libexpat) is susceptible to a software flaw that causes process interruption. When processing a large number of prefixed XML attributes on a single tag can libexpat can terminate unexpectedly due to buffer overrun. The highest threat from this vulnerability is to availability. • http://www.openwall.com/lists/oss-security/2022/01/17/3 https://bugzilla.mozilla.org/show_bug.cgi?id=1217609 https://cert-portal.siemens.com/productcert/pdf/ssa-484086.pdf https://github.com/libexpat/libexpat/issues/531 https://github.com/libexpat/libexpat/pull/534 https://security.gentoo.org/glsa/202209-24 https://security.netapp.com/advisory/ntap-20220121-0004 https://www.debian.org/security/2022/dsa-5073 https://www.tenable.com/security/tns-2022-05 https://acces • CWE-130: Improper Handling of Length Parameter Inconsistency CWE-682: Incorrect Calculation •
CVSS: 10.0EPSS: 96%CPEs: 398EXPL: 30CVE-2021-44228 – Apache Log4j2 Remote Code Execution Vulnerability
https://notcve.org/view.php?id=CVE-2021-44228
Apache Log4j2 2.0-beta9 through 2.15.0 (excluding security releases 2.12.2, 2.12.3, and 2.3.1) JNDI features used in configuration, log messages, and parameters do not protect against attacker controlled LDAP and other JNDI related endpoints. An attacker who can control log messages or log message parameters can execute arbitrary code loaded from LDAP servers when message lookup substitution is enabled. From log4j 2.15.0, this behavior has been disabled by default. From version 2.16.0 (along with 2.12.2, 2.12.3, and 2.3.1), this functionality has been completely removed. Note that this vulnerability is specific to log4j-core and does not affect log4net, log4cxx, or other Apache Logging Services projects. • https://github.com/fullhunt/log4j-scan https://github.com/Puliczek/CVE-2021-44228-PoC-log4j-bypass-words https://github.com/cyberstruggle/L4sh https://github.com/woodpecker-appstore/log4j-payload-generator https://github.com/tangxiaofeng7/apache-log4j-poc https://www.exploit-db.com/exploits/51183 https://www.exploit-db.com/exploits/50592 https://www.exploit-db.com/exploits/50590 https://github.com/logpresso/CVE-2021-44228-Scanner https://github.com/jas502n/Log4j2-CVE-2021-44228 h • CWE-20: Improper Input Validation CWE-400: Uncontrolled Resource Consumption CWE-502: Deserialization of Untrusted Data CWE-917: Improper Neutralization of Special Elements used in an Expression Language Statement ('Expression Language Injection') •
