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

Description

The 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).

Mitigation

Install updates from vendor's website.

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. However, proof of concept for this vulnerability is available.

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

Description

The 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.

Mitigation

Update to version 2.3.16.2.

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. However, a fully functional exploit for this vulnerability is available.

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

Description

The 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.

Mitigation

Update Apache Struts to version 2.3.16.1.
For Apache Commons FileUpload install version 1.3.1.
