Security Bulletin: InfoSphere Data Replication is affected by multiple postgresql vulnerbilities

InfoSphere Data Replication uses postgresql. This bulletin identifies the steps to take to address the vulnerability.

## Vulnerability Details

**CVEID:**CVE-2022-26520
**DESCRIPTION:** pgjdbc could allow a remote attacker to execute arbitrary code on the system, caused by the external control of the java.util.logging.FileHandler component. By sending a specially-crafted request using the loggerFileName connection parameter, an attacker could exploit this vulnerability to create an executable JSP file under a Tomcat web root. Note: the vendor’s position is that there is no pgjdbc vulnerability; instead, it is a vulnerability for any application to use the pgjdbc driver with untrusted connection properties.
CVSS Base score: 9.8
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/222890 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H)

**CVEID:**CVE-2022-21724
**DESCRIPTION:** PostgreSQL JDBC Driver (PgJDBC) could allow a remote authenticated attacker to execute arbitrary code on the system, caused by an unchecked class instantiation when providing plugin classes. By sending a specially-crafted request using the “authenticationPluginClassName”, “sslhostnameverifier”, “socketFactory”, “sslfactory”, “sslpasswordcallback” classes, an attacker could exploit this vulnerability to execute arbitrary code on the system.
CVSS Base score: 8.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/218798 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H)

**CVEID:**CVE-2022-31197
**DESCRIPTION:** PostgreSQL is vulnerable to SQL injection. A remote attacker could send specially-crafted SQL statements to PGJDBC implementation of the java.sql.ResultRow.refreshRow() method, which could allow the attacker to view, add, modify or delete information in the back-end database.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/232820 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N)

**CVEID:**CVE-2020-13692
**DESCRIPTION:** PostgreSQL JDBC Driver could allow a remote authenticated attacker to obtain sensitive information, caused by an XML external entity (XXE) error when processing XML data. By sending specially crafted XML data, a remote attacker could exploit this vulnerability to obtain sensitive information.
CVSS Base score: 6.5
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/183018 for the current score.
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)

**CVEID:**CVE-2022-41946
**DESCRIPTION:** Postgresql JDBC could allow a local authenticated attacker to obtain sensitive information, caused by not limit access to created readable files in the TemporaryFolder. By sending a specially-crafted request, an attacker could exploit this vulnerability to obtain sensitive information, and use this information to launch further attacks against the affected system.
CVSS Base score: 6.3
CVSS Temporal Score: See: https://exchange.xforce.ibmcloud.com/vulnerabilities/240853 for the current score.
CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:N)

**IBM X-Force ID:** 220313
**DESCRIPTION:** PostgreSQL JDBC Driver could allow a remote attacker to gain unauthorized access to the system, caused by the exposure of the connection properties for configuring a pgjdbc connection. By specifying arbitrary connection properties, a remote attacker could exploit this vulnerability to gain unauthorized access to the system.
CVSS Base score: 9.8
