CVSS: 7.8EPSS: 0%CPEs: 14EXPL: 1CVE-2022-1708 – cri-o: memory exhaustion on the node when access to the kube api
https://notcve.org/view.php?id=CVE-2022-1708
A vulnerability was found in CRI-O that causes memory or disk space exhaustion on the node for anyone with access to the Kube API. The ExecSync request runs commands in a container and logs the output of the command. This output is then read by CRI-O after command execution, and it is read in a manner where the entire file corresponding to the output of the command is read in. Thus, if the output of the command is large it is possible to exhaust the memory or the disk space of the node when CRI-O reads the output of the command. The highest threat from this vulnerability is system availability. • https://bugzilla.redhat.com/show_bug.cgi?id=2085361 https://github.com/cri-o/cri-o/commit/f032cf649ecc7e0c46718bd9e7814bfb317cb544 https://github.com/cri-o/cri-o/security/advisories/GHSA-fcm2-6c3h-pg6j https://access.redhat.com/security/cve/CVE-2022-1708 • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •

https://notcve.org/view.php?id=CVE-2022-1677
In OpenShift Container Platform, a user with permissions to create or modify Routes can craft a payload that inserts a malformed entry into one of the cluster router's HAProxy configuration files. This malformed entry can match any arbitrary hostname, or all hostnames in the cluster, and direct traffic to an arbitrary application within the cluster, including one under attacker control. En OpenShift Container Platform, un usuario con permisos para crear o modificar rutas puede diseñar una carga útil que inserte una entrada malformada en uno de los archivos de configuración del router del clúster.

https://notcve.org/view.php?id=CVE-2021-3827
A flaw was found in keycloak, where the default ECP binding flow allows other authentication flows to be bypassed. By exploiting this behavior, an attacker can bypass the MFA authentication by sending a SOAP request with an AuthnRequest and Authorization header with the user's credentials. The highest threat from this vulnerability is to confidentiality and integrity. Se ha encontrado un fallo en keycloak, en el que el flujo de vinculación ECP por defecto permite omitir otros flujos de autenticación. Al explotar este comportamiento, un atacante puede omitir la autenticación MFA mediante el envío de una petición SOAP con un encabezado AuthnRequest y Authorization con las credenciales del usuario. • https://access.redhat.com/security/cve/CVE-2021-3827 https://bugzilla.redhat.com/show_bug.cgi?id=2007512 https://github.com/keycloak/keycloak/commit/44000caaf5051d7f218d1ad79573bd3d175cad0d https://github.com/keycloak/keycloak/security/advisories/GHSA-4pc7-vqv5-5r3v • CWE-287: Improper Authentication •
CVSS: 7.5EPSS: 15%CPEs: 72EXPL: 0CVE-2021-4104 – Deserialization of untrusted data in JMSAppender in Apache Log4j 1.2
https://notcve.org/view.php?id=CVE-2021-4104
JMSAppender in Log4j 1.2 is vulnerable to deserialization of untrusted data when the attacker has write access to the Log4j configuration. The attacker can provide TopicBindingName and TopicConnectionFactoryBindingName configurations causing JMSAppender to perform JNDI requests that result in remote code execution in a similar fashion to CVE-2021-44228. Note this issue only affects Log4j 1.2 when specifically configured to use JMSAppender, which is not the default. Apache Log4j 1.2 reached end of life in August 2015. Users should upgrade to Log4j 2 as it addresses numerous other issues from the previous versions. • http://www.openwall.com/lists/oss-security/2022/01/18/3 https://access.redhat.com/security/cve/CVE-2021-4104 https://github.com/apache/logging-log4j2/pull/608#issuecomment-990494126 https://psirt.global.sonicwall.com/vuln-detail/SNWLID-2021-0033 https://security.gentoo.org/glsa/202209-02 https://security.gentoo.org/glsa/202310-16 https://security.gentoo.org/glsa/202312-02 https://security.gentoo.org/glsa/202312-04 https://security.netapp.com/advisory/ntap-20211223-0007 https&# • CWE-20: Improper Input Validation CWE-502: Deserialization of Untrusted Data •
