CVSS: 8.5EPSS: 2%CPEs: 71EXPL: 1CVE-2021-44832 – Apache Log4j2 vulnerable to RCE via JDBC Appender when attacker controls configuration
https://notcve.org/view.php?id=CVE-2021-44832
Apache Log4j2 versions 2.0-beta7 through 2.17.0 (excluding security fix releases 2.3.2 and 2.12.4) are vulnerable to a remote code execution (RCE) attack when a configuration uses a JDBC Appender with a JNDI LDAP data source URI when an attacker has control of the target LDAP server. This issue is fixed by limiting JNDI data source names to the java protocol in Log4j2 versions 2.17.1, 2.12.4, and 2.3.2. Las versiones de Apache Log4j2 de la 2.0-beta7 a la 2.17.0 (excluyendo las versiones de corrección de seguridad 2.3.2 y 2.12.4) son vulnerables a un ataque de ejecución remota de código (RCE) cuando una configuración utiliza un JDBC Appender con un URI de origen de datos JNDI LDAP cuando un atacante tiene el control del servidor LDAP de destino. Este problema se soluciona limitando los nombres de fuentes de datos JNDI al protocolo java en las versiones 2.17.1, 2.12.4 y 2.3.2 de Log4j2 Apache Log4j2 versions 2.0-beta7 through 2.17.0 (excluding security fix releases 2.3.2 and 2.12.4) are vulnerable to a remote code execution (RCE) attack where an attacker with permission to modify the logging configuration file can construct a malicious configuration using a JDBC Appender with a data source referencing a JNDI URI which can execute remote code. This issue is fixed by limiting JNDI data source names to the java protocol in Log4j2 versions 2.17.1, 2.12.4, and 2.3.2. • https://github.com/thedevappsecguy/Log4J-Mitigation-CVE-2021-44228--CVE-2021-45046--CVE-2021-45105--CVE-2021-44832 http://www.openwall.com/lists/oss-security/2021/12/28/1 https://cert-portal.siemens.com/productcert/pdf/ssa-784507.pdf https://issues.apache.org/jira/browse/LOG4J2-3293 https://lists.apache.org/thread/s1o5vlo78ypqxnzn6p8zf6t9shtq5143 https://lists.debian.org/debian-lts-announce/2021/12/msg00036.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject • CWE-20: Improper Input Validation CWE-74: Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection') •
CVSS: 7.5EPSS: 0%CPEs: 44EXPL: 0CVE-2021-45485 – kernel: information leak in the IPv6 implementation
https://notcve.org/view.php?id=CVE-2021-45485
In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses. En la implementación de IPv6 en el kernel de Linux versiones anteriores a 5.13.3, el archivo net/ipv6/output_core.c presenta un filtrado de información debido a determinado uso de una tabla hash que, aunque es grande, no considera apropiadamente que atacantes basados en IPv6 pueden elegir típicamente entre muchas direcciones de origen IPv6 An information leak flaw was found in the Linux kernel’s IPv6 implementation in the __ipv6_select_ident in net/ipv6/output_core.c function. The use of a small hash table in IP ID generation allows a remote attacker to reveal sensitive information. • https://arxiv.org/pdf/2112.09604.pdf https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.13.3 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=62f20e068ccc50d6ab66fdb72ba90da2b9418c99 https://security.netapp.com/advisory/ntap-20220121-0001 https://www.oracle.com/security-alerts/cpujul2022.html https://access.redhat.com/security/cve/CVE-2021-45485 https://bugzilla.redhat.com/show_bug.cgi?id=2039911 • CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
