Description
This security bulletin contains information about 3 vulnerabilities.
1) Path traversal (CVE-ID: CVE-2023-39143)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to perform directory traversal attacks.
The vulnerability exists due to input validation error when processing directory traversal sequences in the applications API interface. A remote non-authenticated attacker can send a specially crafted HTTP request and read or write arbitrary files on the system.
2) Resource exhaustion (CVE-ID: CVE-2023-3486)
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. A remote attacker can trigger resource exhaustion by exhausting all available disk space and perform a denial of service (DoS) attack.
3) Improper initialization (CVE-ID: CVE-2022-21724)
CWE-ID: CWE-665 - Improper Initialization
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to escalate privileges on the system.
The vulnerability exists due to improper initialization in pgjdbc driver when handling attacker-controlled URL in connection properties as the driver does not verify if the class implements the expected interface before instantiating the class. A remote attacker can pass specially crafted URL to the affected application and execute arbitrary code in the system.
