Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Type Traversal Vulnerability
EUVDB-ID: #VU5046
Risk: Medium
CVSSv3.1: 8.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:F/RL:O/RC:C]
CVE-ID: CVE-2014-0257
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to bypass certain security restrictions.
The weakness exists due to the failure to properly verify safety of a method for execution within Microsoft .NET Framework. A remote attacker can run a specially crafted Web site, trick the victim into visiting it and gain elevated privileges and execute arbitrary code.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.
Install update from vendor's website.
Microsoft .NET Framework: 1.1 - 4.5.1

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.
2) Denial of service
EUVDB-ID: #VU5042
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2014-0253
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause DoS conditions on the target system.
The weakness exists due to the failure to properly identify stale or closed HTTP client connections within Microsoft ASP.NET. By sending a specially crafted HTTP POST request, a remote attacker can cause the server to stop responding.
Successful exploitation of the vulnerability may allow an attacker to perform denial of service (DoS) attack.

3) ASLR bypass
EUVDB-ID: #VU5029
Risk: High
CVSSv3.1: 6.9 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:N/A:N/E:F/RL:O/RC:C]
CVE-ID: CVE-2014-0295
CWE-ID:
CWE-264 - Permissions, Privileges, and Access Controls
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass security restrictions on the target system.
The weakness exists due to missing Address Space Layout Randomization (ASLR) features in certain components. A remote attacker can create a specially crafted Web site, trick the victim into opening it, bypass security restrictions and execute another attack.
Successful exploitation of the vulnerability results in security bypass on the vulnerable system.
Note: the vulnerability was being actively exploited.
