Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Deserialization of untrusted data

EUVDB-ID: #VU10610

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2018-5968

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code.

The weakness exists due to deserialization flaw. A remote attacker can supply specially crafted input, execute arbitrary code and bypass a blacklist on the target system.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Update to version 2.8.11.1 or 2.9.4.

Vulnerable software versions

jackson-databind: 2.8.0 - 2.9.3

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) Deserialization of untrusted data

EUVDB-ID: #VU11268

Risk: High

CVSSv4.0: 7.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2018-7489

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

Exploit availability: No

Description

The vulnerability allows a remote unauthenticated attacker to bypass security restrictions and execute arbitrary code on the target system.

The weakness exists in the readValue method due to improper validation of user-input. A remote attacker can send malicious JSON input, bypass security restrictions and execute arbitrary code with elevated privileges.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Update to version 2.8.11.1.

Vulnerable software versions

jackson-databind: 2.0.0 - 2.9.4
