1) Deserialization of untrusted data

EUVDB-ID: #VU10257

Risk: High

CVSSv3.1: 9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:P/RL:O/RC:C]

CVE-ID: CVE-2017-17485

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 weakness exists in the FasterXML jackson-databind library due to improper validation of user-input handled by the readValue method of the ObjectMapper object. A remote attacker can send malicious input to the vulnerable method of a web application that uses the Spring library in the application's classpath and execute arbitrary code with elevated privileges.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Update the affected package to version: 2.4.2-2+deb8u3, 2.8.6-1+deb9u3

Vulnerable software versions

Debian Linux: All versions
