Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Path traversal
EUVDB-ID: #VU8569
Risk: Medium
CVSSv3.1: 5.1 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2016-2097
CWE-ID:
CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to read arbitrary files on the system.
The vulnerability exists due to improper input validation in Action View. A remote attacker can send a specially crafted request, containing directory traversal sequences (e.g. "../") and view contents of arbitrary file on vulnerable system.
The vulnerability exists due to incomplete fix of SB2016021701.
Update the affected package to version: 2:4.1.8-1+deb8u2, 2:4.2.5.2-1, 2:4.2.5.2-1
Vulnerable software versionsDebian Linux: All versions

2) Code injection
EUVDB-ID: #VU8567
Risk: High
CVSSv3.1: 9.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:F/RL:O/RC:C]
CVE-ID: CVE-2016-2098
CWE-ID:
CWE-94 - Improper Control of Generation of Code ('Code Injection')
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to improper input validation in "render()" function. A remote attacker can send a specially crafted request to the vulnerable application and execute arbitrary code on the target system.
Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.
