Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Deserialization of Untrusted Data
EUVDB-ID: #VU61937
Risk: Critical
CVSSv3.1: 8.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2021-42392
CWE-ID:
CWE-502 - Deserialization of Untrusted Data
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data within the org.h2.util.JdbcUtils.getConnection method. A remote attacker can pass a JNDI driver name and a URL leading to a LDAP or RMI servers and execute arbitrary code on the system.

2) Deserialization of Untrusted Data
EUVDB-ID: #VU61938
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-23221
CWE-ID:
CWE-502 - Deserialization of Untrusted Data
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data within jdbc:h2:mem. A remote attacker can pass specially crafted JDBC URL containing the IGNORE_UNKNOWN_SETTINGS=TRUE;FORBID_CREATION=FALSE;INIT=RUNSCRIPT substring to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
