VULNERABILITIES FOR WHICH EXPLOITS ARE AVAILABLE
MOST PREVALENT MALWARE FILES 2017-03-14 - 2017-03-21
Title: Cisco Releases Critical Security Advisory For IOS and IOS XE 0-day Found in “Vault 7” Info Dump
Description: Cisco has released a critical security advisory in response to CVE-2017-3881, a 0-day vulnerability that was identified in the “Vault 7” information dump. CVE-2017-3881 is a remote code execution vulnerability that manifests in the Cisco Cluster Management Protocol (CMP) processing functionality of IOS and IOS XE. A remote, unauthenticated attacker who transmits malformed CMP-specific Telnet options to a vulnerable device could exploit this flaw and execute arbitrary code with elevated privileges. Note that the vulnerable device must be configured to accept Telnet connections. Cisco is currently developing software updates that will address this vulnerability.

Title: Various JSON Library Patched to Address Invalid Curve Crypto Attack
Description: Several JSON libraries have been patched to address a flaw in the implementation of JSON Web Encryption (JWE). Specifically, libraries that implement JWE for encryption with Key Agreement with Elliptic Curve Diffie-Hellman Ephemeral Static (ECDH-ES) were found to be vulnerable to an Invalid Curve Attack. This means that recovery of the private key could be possible. In response to this flaw being identified, go-jose, jose2go, Nimbus JOSE+WT, node-jose, and jose4 JSON libraries were all patched.

ID: CVE-2017-5638
Title: Apache Struts2 Input Validation Code Execution Vulnerability
Vendor: Apache
Description: The Jakarta Multipart parser in Apache Struts 2 2.3.x before 2.3.32 and 2.5.x before 2.5.10.1 mishandles file upload, which allows remote attackers to execute arbitrary commands via a #cmd= string in a crafted Content-Type HTTP header, as exploited in the wild in March 2017.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2016-9244
Title: F5 BIG-IP SSL Information Disclosure Vulnerability
Vendor: F5
Description: A BIG-IP virtual server configured with a Client SSL profile that has the non-default Session Tickets option enabled may leak up to 31 bytes of uninitialized memory. A remote attacker may exploit this vulnerability to obtain Secure Sockets Layer (SSL) session IDs from other sessions. It is possible that other data from uninitialized memory may be returned as well.
CVSS v2 Base Score: 5.0 (AV:N/AC:L/Au:N/C:P/I:N/A:N)
ID: CVE-2017-3823
Title: Cisco WebEx Google Chrome Extension Remote Code Execution Vulnerability
Vendor: Cisco
Description: An issue was discovered in the Cisco WebEx Extension before 1.0.7 on Google Chrome, the ActiveTouch General Plugin Container before 106 on Mozilla Firefox, the GpcContainer Class ActiveX control plugin before 10031.6.2017.0126 on Internet Explorer, and the Download Manager ActiveX control plugin before 2.1.0.10 on Internet Explorer. A vulnerability in these Cisco WebEx browser extensions could allow an unauthenticated, remote attacker to execute arbitrary code with the privileges of the affected browser on an affected system. This vulnerability affects the browser extensions for Cisco WebEx Meetings Server and Cisco WebEx Centers (Meeting Center, Event Center, Training Center, and Support Center) when they are running on Microsoft Windows. The vulnerability is a design defect in an application programing interface (API) response parser within the extension. An attacker that can convince an affected user to visit an attacker-controlled web page or follow an attacker-supplied link with an affected browser could exploit the vulnerability. If successful, the attacker could execute arbitrary code with the privileges of the affected browser.
