Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) UNIX symbolic link following

EUVDB-ID: #VU54943

Risk: Low

CVSSv3.1: 6.2 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2013-0248

CWE-ID: CWE-61 - UNIX Symbolic Link (Symlink) Following

Exploit availability: No

Description

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to a symlink following issue. The application uses the /tmp directory for uploaded files. A local user can create a specially crafted symbolic link to a critical file on the system and overwrite it with privileges of the application.

Successful exploitation of this vulnerability may result in privilege escalation.

Mitigation

Install update from vendor's website.

Q & A

Can this vulnerability be exploited remotely?

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Resource exhaustion

EUVDB-ID: #VU197

Risk: Medium

CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-3092

CWE-ID: CWE-400 - Resource exhaustion

Exploit availability: No

Description

The vulnerability allows a remote attacker to cause denial of service conditions on the target system.

The vulnerability exists due to input validation error when processing very long boundary strings within the MultipartStream class in Apache Commons Fileupload. A remote user can cause denial of service conditions by sending specially crafted boundary string and consume excessive CPU resources.

Successful exploitation of this vulnerability may result in denial of service attack.

Mitigation

Install update 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.

3) Desereliazation of untrusted data

EUVDB-ID: #VU12312

Risk: High

CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-1000031

CWE-ID: CWE-502 - Deserialization of Untrusted Data

Exploit availability: No

Description

The vulnerability allows a remote unauthenticated attacker to execute arbitrary code on the target system.

The weakness exists in DiskFileItem class of the FileUpload library due to deserialization of untrusted data. A remote attacker can execute arbitrary code under the context of the current process.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Install update from vendor's website.

4) 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

Install update from vendor's website.

5) Input validation error

EUVDB-ID: #VU81098

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2013-2186

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to overwrite arbitrary files on the system.

The vulnerability exists due to insufficient validation of user-supplied input when processing file names with a NULL byte within the DiskFileItem class. A remote attacker can upload a specially crafted file with a NULL byte in its name and overwrite arbitrary files on the system.

Mitigation

Install update from vendor's website.
