Description
This security bulletin contains information about 2 vulnerabilities.
1) Privilege escalation (CVE-ID: CVE-2018-12539)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a local unauthenticated attacker to gain elevated privileges on the target system.
The weakness exists due to the failure to restrict the use of Java Attach API to connect to an Eclipse OpenJ9 or IBM JVM on the same machine and use Attach API operations to only the process owner. A local attacker can conduct directory traversal attack and extract compressed dump files.
2) Path traversal (CVE-ID: CVE-2018-1656)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:A/VC:N/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote attacker to conduct directory traversal attack on the target system.
The weakness exists due to insufficient protection of path traversal attacks when extracting compressed dump files. A remote attacker can conduct directory traversal attack and extract compressed dump files.
