Description
This security bulletin contains information about 3 vulnerabilities.
1) Code Injection (CVE-ID: CVE-2020-1953)
CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure configuration of third-party library for parsing YAML files. A remote attacker with ability to pass YAML file to the application can inject and execute arbitrary code on the system.
2) Cleartext storage of sensitive information (CVE-ID: CVE-2020-10727)
CWE-ID: CWE-312 - Cleartext Storage of Sensitive Information
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local user to gain access to passwords of application users.
The vulnerability exists due to ActiveMQ Artemis management API stores passwords in plaintext in the Artemis shadow file (etc/artemis-users.properties file) when executing the `resetUsers` operation. A local user can view contents of the Artemis shadow file and obtain passwords of application users.
3) Resource exhaustion (CVE-ID: CVE-2020-11612)
CWE-ID: CWE-400 - Resource exhaustion
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
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 within ZlibDecoders in Netty while decoding a ZlibEncoded byte stream. A remote attacker can trigger resource exhaustion by passing an overly large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.
