Description
This security bulletin contains information about 8 secuirty vulnerabilities.
1) Integer overflow (CVE-ID: CVE-2020-27813)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to integer overflow when processing frames received via a websocket connection. A remote attacker can pass specially crafted data to the application, trigger integer overflow and perform a denial of service (DoS) attack.
2) Input validation error (CVE-ID: CVE-2020-28362)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input in a number of math/big.Int methods (Div, Exp, DivMod, Quo, Rem, QuoRem, Mod, ModInverse, ModSqrt, Jacobi, and GCD). A remote attacker can pass large input data to the application, specifically as divisor or modulo argument larger than 3168 bits (on 32-bit architectures) or 6336 bits (on 64-bit architectures).
3) Incorrect calculation (CVE-ID: CVE-2021-3114)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to incorrect calculation performed by the application in "crypto/elliptic/p224.go". A remote attacker can generate incorrect outputs, related to an underflow of the lowest limb during the final complete reduction in the P-224 field.
4) Input validation error (CVE-ID: CVE-2021-21639)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the affected software does not validate the type of object created after loading the data submitted to the "config.xml" REST API endpoint of a node. A remote authenticated attacker can replace a node with one of a different type.
5) Improper Authentication (CVE-ID: CVE-2021-21640)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to the affected software does not properly check that a newly created view has an allowed name. A remote authenticated attacker can create views with invalid or already-used names.
6) Information disclosure (CVE-ID: CVE-2021-28163)
The vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to excessive data output by the application. If the ${jetty.base} directory or the ${jetty.base}/webapps directory is a symlink, the contents of the ${jetty.base}/webapps directory may be deployed as a static web application, exposing the content of the directory for download.
7) Resource exhaustion (CVE-ID: CVE-2021-28165)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources when processing large TLS frames. A remote attacker can send specially crafted data to the server, trigger CPU high load and perform a denial of service (DoS) attack.
8) Security features bypass (CVE-ID: CVE-2021-30465)
The vulnerability allows a remote attacker to compromise the target system.
The vulnerability exists due to the security features bypass issue. A remote authenticated attacker on the local network can perform a symlink exchange attack and host filesystem being bind-mounted into the container.
