RECENT VULNERABILITIES FOR WHICH EXPLOITS ARE AVAILABLE
COMPILED BY THE QUALYS VULNERABILITY RESEARCH TEAM
This is a list of recent vulnerabilities for which exploits are available. System administrators can use this list to help in prioritization of their remediation activities. The Qualys Vulnerability Research Team compiles this information based on various exploit frameworks, exploit databases, exploit kits and monitoring of internet activity.
ID: CVE-2017-0037
Title: Microsoft Internet Explorer Remote Code Execution (MS17-007)
Vendor: Microsoft
Description: Microsoft Internet Explorer 10 and 11 and Microsoft Edge have a type confusion issue in the Layout::MultiColumnBoxBuilder::HandleColumnBreakOnColumnSpanningElement function in mshtml.dll, which allows remote attackers to execute arbitrary code via vectors involving a crafted Cascading Style Sheets (CSS) token sequence and crafted JavaScript code that operates on a TH element.
CVSS v2 Base Score: 7.6 (AV:N/AC:H/Au:N/C:C/I:C/A:C)
ID: CVE-2017-0145
Title: Microsoft Windows SMB Remote Code Execution Vulnerability
Vendor: Microsoft
Description: The SMBv1 server in Microsoft Windows Vista SP2; Windows Server 2008 SP2 and R2 SP1; Windows 7 SP1; Windows 8.1; Windows Server 2012 Gold and R2; Windows RT 8.1; and Windows 10 Gold, 1511, and 1607; and Windows Server 2016 allows remote attackers to execute arbitrary code via crafted packets, aka “Windows SMB Remote Code Execution Vulnerability.” This vulnerability is different from those described in CVE-2017-0143, CVE-2017-0144, CVE-2017-0146, and CVE-2017-0148.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2017-0290
Title: Microsoft Malware Protection Engine Remote Code Execution Vulnerability
Vendor: Microsoft
Description: NScript in mpengine in Microsoft Malware Protection Engine with Engine Version before 1.1.13704.0, as used in Windows Defender and other products, allows remote attackers to execute arbitrary code or cause a denial of service (type confusion and application crash) via crafted JavaScript code within any file scanned by this engine.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2017-3881
Title: Cisco IOS and IOS XE Software Cluster Management Protocol Remote Code Execution Vulnerability
Vendor: Cisco
Description: A vulnerability in the Cisco Cluster Management Protocol (CMP) processing code in Cisco IOS and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a reload of an affected device or remotely execute code with elevated privileges. The Cluster Management Protocol utilizes Telnet internally as a signaling and command protocol between cluster members. The vulnerability is due to the combination of two factors: (1) the failure to restrict the use of CMP-specific Telnet options only to internal, local communications between cluster members and instead accept and process such options over any Telnet connection to an affected device; and (2) the incorrect processing of malformed CMP-specific Telnet options. An attacker could exploit this vulnerability by sending malformed CMP-specific Telnet options while establishing a Telnet session with an affected Cisco device configured to accept Telnet connections. An exploit could allow an attacker to execute arbitrary code and obtain full control of the device or cause a reload of the affected device. This affects Catalyst switches, Embedded Service 2020 switches, Enhanced Layer 2 EtherSwitch Service Module, Enhanced Layer 2/3 EtherSwitch Service Module, Gigabit Ethernet Switch Module (CGESM) for HP, IE Industrial Ethernet switches, ME 4924-10GE switch, RF Gateway 10, and SM-X Layer 2/3 EtherSwitch Service Module. Cisco Bug IDs: CSCvd48893.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2017-7269
Title: Microsoft IIS 6.0 ScStoragePathFromUrl Buffer Overflow Vulnerability
Vendor: Microsoft
Description: Buffer overflow in the ScStoragePathFromUrl function in the WebDAV service in Internet Information Services (IIS) 6.0 in Microsoft Windows Server 2003 R2 allows remote attackers to execute arbitrary code via a long header beginning with “If: <http://“ in a PROPFIND request, as exploited in the wild in July or August 2016.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
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-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.
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)
ID: CVE-2016-7892
Title: Adobe Flash Player Use-After-Free Code Execution Vulnerability
Vendor: Adobe
Description: Remote exploitation of a use-after-free vulnerability in Adobe’s Flash Player could allow attackers to execute arbitrary code. Adobe is aware of a report that an exploit for CVE-2016-7892 exists in the wild, and is being used in limited targeted attacks.
CVSS v2 Base Score: 9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)
ID: CVE-2016-6366
Title: Cisco Adaptive Security Appliance SNMP Buffer Overflow Code Execution Vulnerability
Vendor: Cisco
Description: Buffer overflow in Cisco Adaptive Security Appliance (ASA) Software through 9.4.2.3 on ASA 5500, ASA 5500-X, ASA Services Module, ASA 1000V, ASAv, Firepower 9300 ASA Security Module, PIX, and FWSM devices allows remote authenticated users to execute arbitrary code via crafted IPv4 SNMP packets, aka Bug ID CSCva92151 or EXTRABACON.
CVSS v2 Base Score: 8.5 (AV:N/AC:M/Au:S/C:C/I:C/A:C)
