Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Deserialization of Untrusted Data

EUVDB-ID: #VU19018

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-2019-12384

CWE-ID: CWE-502 - Deserialization of Untrusted Data

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to software allows the logback-core class to process polymorphic deserialization. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Update the affected package to version: 2.8.6-1+deb9u6, 2.9.8-3+deb10u1.

Vulnerable software versions

jackson-databind (Debian package): 2.8.5-1 - 2.9.8-3

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Information disclosure

EUVDB-ID: #VU19937

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-14439

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a polymorphic typing issue when Default Typing is enabled for an externally exposed JSON endpoint and the service has the logback jar in the classpath. A remote attacker can send a specially crafted JSON message and gain unauthorized access to sensitive information on the system.

Mitigation

Update the affected package to version: 2.8.6-1+deb9u6, 2.9.8-3+deb10u1.

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.

4) Information disclosure

EUVDB-ID: #VU21136

Risk: Medium

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-16335

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows a remote attacker to gain access to potentially sensitive information.

The vulnerability exists due to a polymorphic typing issue in the "com.zaxxer.hikari.HikariDataSource". A remote attacker can gain unauthorized access to sensitive information on the system.

5) Input validation error

EUVDB-ID: #VU21580

Risk: Medium

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-16942

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to compromise the affected application.

The vulnerability exists due to a Polymorphic Typing issue when processing JSON requests  within the org.apache.commons.dbcp.datasources.SharedPoolDataSource and org.apache.commons.dbcp.datasources.PerUserPoolDataSourc components. A remote attacker can send specially crafted JSON data to an RMI service endpoint and execute arbitrary code on he system.

Successful exploitation of the vulnerability requires that Default Typing is enabled (either globally or for a specific property) for an externally exposed JSON endpoint, the service has the commons-dbcp (1.4) jar in the classpath, and an attacker can find an RMI service endpoint to send requests to.
