CVSS: 5.9EPSS: 96%CPEs: 213EXPL: 7CVE-2021-45105 – Apache Log4j2 does not always protect from infinite recursion in lookup evaluation
https://notcve.org/view.php?id=CVE-2021-45105
Apache Log4j2 versions 2.0-alpha1 through 2.16.0 (excluding 2.12.3 and 2.3.1) did not protect from uncontrolled recursion from self-referential lookups. This allows an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This issue was fixed in Log4j 2.17.0, 2.12.3, and 2.3.1. Apache Log4j2 versiones 2.0-alpha1 hasta 2.16.0 (excluyendo las versiones 2.12.3 y 2.3.1) no protegían de la recursión no controlada de las búsquedas autorreferenciales. Esto permite a un atacante con control sobre los datos de Thread Context Map causar una denegación de servicio cuando es interpretada una cadena diseñada. • https://github.com/thedevappsecguy/Log4J-Mitigation-CVE-2021-44228--CVE-2021-45046--CVE-2021-45105--CVE-2021-44832 https://github.com/tejas-nagchandi/CVE-2021-45105 https://github.com/pravin-pp/log4j2-CVE-2021-45105 https://github.com/dileepdkumar/https-github.com-pravin-pp-log4j2-CVE-2021-45105-1 https://github.com/dileepdkumar/https-github.com-pravin-pp-log4j2-CVE-2021-45105 https://github.com/dileepdkumar/https-github.com-dileepdkumar-https-github.com-pravin-pp-log4j2-CVE-2021-45105-v htt • CWE-20: Improper Input Validation CWE-674: Uncontrolled Recursion •
CVSS: 8.3EPSS: 1%CPEs: 248EXPL: 4CVE-2021-2351 – Oracle Database Weak NNE Integrity Key Derivation
https://notcve.org/view.php?id=CVE-2021-2351
Vulnerability in the Advanced Networking Option component of Oracle Database Server. Supported versions that are affected are 12.1.0.2, 12.2.0.1 and 19c. Difficult to exploit vulnerability allows unauthenticated attacker with network access via Oracle Net to compromise Advanced Networking Option. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Advanced Networking Option, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Advanced Networking Option. • http://packetstormsecurity.com/files/165255/Oracle-Database-Protection-Mechanism-Bypass.html http://packetstormsecurity.com/files/165258/Oracle-Database-Weak-NNE-Integrity-Key-Derivation.html http://seclists.org/fulldisclosure/2021/Dec/19 http://seclists.org/fulldisclosure/2021/Dec/20 https://www.oracle.com/security-alerts/cpuapr2022.html https://www.oracle.com/security-alerts/cpujan2022.html https://www.oracle.com/security-alerts/cpujan2023.html https://www.oracle.com/security-alerts/cpujul2021.html https:&# • CWE-327: Use of a Broken or Risky Cryptographic Algorithm CWE-384: Session Fixation •

In Apache Commons IO before 2.7, When invoking the method FileNameUtils.normalize with an improper input string, like "//../foo", or "\\..\foo", the result would be the same value, thus possibly providing access to files in the parent directory, but not further above (thus "limited" path traversal), if the calling code would use the result to construct a path value.
