CVEs For Which Public Exploits Have Been Detected

ID:        CVE-2019-11043
Title:    PHP 7 Remote Code Execution Vulnerability
Vendor:    Multi-Vendor
Description: The vulnerability resides in the "env_path_info" underflow in PHP-FPM . It contains pointer arithmetics that assumes that env_path_info has a prefix equal to the path to the php script. However, the code does not check this assumption is satisfied. The absence of the check can lead to an invalid pointer in the "path_info" variable. The vulnerability allows an attacker to run arbitrary commands on a vulnerable server by a specially crafted URL.  
CVSS v2 Base Score:    9.3 (AV:N/AC:M/Au:N/C:C/I:C/A:C)

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-2019-7609
Title:    Kibana Timelion Remote Code Execution Vulnerability
Vendor:    Elastic
Description: Kibana Timelion visualizer is exposed to an arbitrary code execution vulnerability. An attacker with access to the Timelion application could send a request that will attempt to execute javascript code. This could possibly lead to an attacker executing arbitrary commands with permissions of the Kibana process on the host system.
CVSS v2 Base Score:    10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID:        CVE-2019-14287
Title:    SUDO Security Policy Bypass Vulnerability
Vendor:    Multi-Vendor
Description: When sudo is configured to allow a user to run commands as an arbitrary user via the ALL keyword in a Runas specification, it is possible to run commands as root by specifying the user ID -1 or 4294967295.  This can be used by a user with sufficient sudo privileges to run commands as root even if the Runas specification explicitly disallows root access, as long as the ALL keyword is listed first in the Runas specification. For example, this allows bypass of !root configuration, and USER= logging, for a "sudo -u #$((0xffffffff))" command. An attacker with access to a Runas ALL sudoer account can bypass certain policy blacklists and session PAM modules, and can cause incorrect logging, by invoking sudo with a crafted user ID.
CVSS v2 Base Score:    9.0 (AV:N/AC:L/Au:S/C:C/I:C/A:C)

ID:        CVE-2019-1306
Title:    Azure DevOps and Team Foundation Server Remote Code Execution Vulnerability
Vendor:    Microsoft
Description:  Remote code execution vulnerability exists when Azure DevOps Server (ADO) and Team Foundation Server (TFS) fail to validate input properly. An attacker who successfully exploited this vulnerability could execute code on the server in the context of the TFS or ADO service account. To exploit the vulnerability, an attacker would need to upload a specially crafted file to a vulnerable ADO or TFS server repo and wait for the system to index the file.
CVSS v2 Base Score:    7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)

ID:        CVE-2019-8460
Title:    OpenBSD TCP SACK Denial of Service Vulnerability
Vendor:    OpenBSD
Description: OpenBSD kernel can be forced to create long chains of TCP SACK holes that cause very expensive calls to tcp_sack_option() for every incoming SACK packet which can lead to a denial of service vulnerability. The SACK holes sorted list is bounded in the TCP established state of the connection by (1) the size of the pool (up to 32K entries), and (2) by the TCP retransmit timer (whose interval could be up to 64 seconds). This means that an attacker could manipulate the connection's window scaling and RTT, forcing the victim to send a large amount of not-ACKed data and increase its retransmission timeout. This in turn enables the attacker to send a large number of SACKs. As the sorted list of SACK holes becomes larger, inserting additional elements becomes more expensive, resulting in higher and higher CPU consumption that may eventually lead to a denial of service vulnerability.
CVSS v2 Base Score:    5.0 (AV:N/AC:L/Au:N/C:N/I:N/A:P)

ID:        CVE-2019-10149
Title:    Exim Remote Command Execution Vulnerability
Vendor:    Exim
Description: Exim is exposed to remote command execution vulnerability. Successfully exploiting this issue may allow an attacker to execute arbitrary commands as root. Improper validation of recipient address in deliver message() function in /src/deliver.c may lead to remote command execution.
CVSS v2 Base Score:    7.5 (AV:N/AC:L/Au:N/C:P/I:P/A:P)

ID:        CVE-2019-16920
Title:    D-Link Unauthenticated Remote Code Execution Vulnerability
Vendor:    D-Link
Description: Unauthenticated remote code execution occurs in D-Link products. The issue occurs when the attacker sends an arbitrary input to a "PingTest" device common gateway interface that could lead to common injection. An attacker who successfully triggers the command injection could achieve full system compromise.
