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-2019-13720
Title: Google Chrome Use-After-Free Vulnerability
Vendor: Google
Description: Google Chrome is exposed to a Use-After-Free vulnerability in audio. The exploit uses a race condition between two threads due to missing proprer synchronization between them. It gives an attacker a Use-After-Free condition that could lead to code execustion scenarios.
CVSS v2 Base Score: | 10 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2019-2114
Title: NFC Beaming Android Security Control Bypass Vulnerability
Vendor: Google
Description: NFC beaming of applications between devices using Android OS bypasses some security controls (the “install unknown application” prompt). This could lead to local escalation of privilege by installing an application with no additional execution privileges needed. This means, that an Android phone that has NFC and Android Beam enabled, then touching a malicious phone or a malicious NFC payment terminal to the device may allow malware to be installed by bypassing the “install unknown apps” prompt.
CVSS v2 Base Score: | 4.4 (AV:L/AC:M/Au:N/C:P/I:P/A:P)
ID: CVE-2019-11932
Title: Whatsapp Remote Code Execution Vulnerability
Vendor: Whatsapp
Description: A double free vulnerability exists in the DDGifSlurp function in decoding.c in libpl_droidsonroids_gif as used in WhatsApp for Android before 2.19.244. Successful exploitation allows remote attackers to execute arbitrary code or cause a denial of service.

ID: CVE-2019-11043
Title: PHP 7 Remote Code Execution Vulnerability
Vendor: Multi-Vendor
Description: A vulenrabilty exists in PHP where insufficient validation in the path handling code of FPM module could result in the execution of arbitrary code and to write past allocated buffers into the space reserved for FCGI protocol data, thus opening the possibility of remote code execution. This vulnerability could be exploited to gain partial access to sensitive information. Malicious users could also use this vulnerability to change partial contents or configuration on the system.
CVSS v2 Base Score: | 7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)
ID: CVE-2019-16662
Title: rConfig Remote Code Execution Vulnerability
Vendor: Multi-Vendor
Description: An issue was discovered in rConfig where an attacker can directly execute system commands by sending a GET request to ajaxServerSettingsChk.php because the rootUname parameter is passed to the exec function without filtering, which can lead to command execution
CVSS v2 Base Score: | 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)
ID: CVE-2019-1414
Title: Visual Studio Code Elevation of Privilege Vulnerability
Vendor: Microsoft
Description: An elevation of privilege vulnerability exists in Visual Studio Code when it exposes a debug listener to users of a local computer. A local attacker who successfully exploited the vulnerability could inject arbitrary code to run in the context of the current user. If the current user is logged on with administrative user rights, an attacker could take control of the affected system.
CVSS v2 Base Score: | 6.3 (AV:L/AC:M/Au:N/C:C/I:C/A:N)
ID: CVE-2019-2888
