Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Permissions, Privileges, and Access Controls
EUVDB-ID: #VU68588
Risk: High
CVSSv3.1: 8.8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2014-0112
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to compromise the affected system.
The vulnerability exists due to improper access restrictions within the getClass method in ParametersInterceptor. A remote non-authenticated attacker can manipulate the ClassLoader via a specially crafted request and execute arbitrary code on the system.
Note, the vulnerability exists due to incomplete fix for #VU5234 (CVE-2014-0094).

2) Security bypass
EUVDB-ID: #VU5234
Risk: Critical
CVSSv3.1: 4.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N/E:F/RL:O/RC:C]
CVE-ID: CVE-2014-0094
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to bypass security restsrictions on the target system.
The weakness exists due to an error in ParametersInterceptor. A remote attacker can use a specially crafted class parameter to manipulate the ClassLoader used by the application server.
Successful exploitation of the vulnerability results in security bypass on the vulnerable system.
Note: the vulnerability was being actively exploited.
Update to version 2.3.16.2.

3) Infinite loop
EUVDB-ID: #VU5233
Risk: Medium
CVSSv3.1: 8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H/E:F/RL:O/RC:C]
CVE-ID: CVE-2014-0050
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to cause DoS conditions on the target system.
The weakness exists due to boundary error when handling Content-Type HTTP header for multipart requests. By sending a specially crafted Content-Type header, containing 4092 characters in "boundary" field, a remote attacker can cause the application to enter into an infinite loop.
Successful exploitation of the vulnerability results in denial of service on the vulnerable system.
Note: the vulnerability was being actively exploited.
Update Apache Struts to version 2.3.16.1.
For Apache Commons FileUpload install version 1.3.1.
