1) XML injection

EUVDB-ID: #VU48940

Risk: High

CVSSv3.1:

CVE-ID: CVE-2020-29599

CWE-ID: CWE-91 - XML Injection

Exploit availability: Yes

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

ImageMagick before 6.9.11-40 and 7.x before 7.0.10-40 mishandles the -authenticate option, which allows setting a password for password-protected PDF files. The user-controlled password was not properly escaped/sanitized and it was therefore possible to inject additional shell commands via coders/pdf.c.

Mitigation

Install update from vendor's website.
