CVE-2018-1168: ZDI-18-141

This vulnerability allows local attackers to escalate privileges on vulnerable installations of ABB MicroSCADA 9.3 with FP 1-2-3. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the configuration of the access controls for the installed product files. The installation procedure leaves critical files open to manipulation by any authenticated user. An attacker can leverage this vulnerability to escalate privileges to SYSTEM. Was ZDI-CAN-5097.

CVE-2017-18079

drivers/input/serio/i8042.c in the Linux kernel before 4.12.4 allows attackers to cause a denial of service (NULL pointer dereference and system crash) or possibly have unspecified other impact because the port->exists value can change after it is validated.

CVE-2017-17806

The HMAC implementation (crypto/hmac.c) in the Linux kernel before 4.14.8 does not validate that the underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AF_ALG-based hash interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel stack buffer overflow by executing a crafted sequence of system calls that encounter a missing SHA-3 initialization.

CVE-2017-15583

The embedded web server on ABB Fox515T 1.0 devices is vulnerable to Local File Inclusion. It accepts a parameter that specifies a file for display or for use as a template. The filename is not validated; an attacker could retrieve any file.

CVE-2017-2820: TALOS-2017-0321 || Cisco Talos Intelligence Group

An exploitable integer overflow vulnerability exists in the JPEG 2000 image parsing functionality of freedesktop.org Poppler 0.53.0. A specially crafted PDF file can lead to an integer overflow causing out of bounds memory overwrite on the heap resulting in potential arbitrary code execution. To trigger this vulnerability, a victim must open the malicious PDF in an application using this library.

CVE-2017-2863: TALOS-2017-0367 || Cisco Talos Intelligence Group

An out-of-bounds write vulnerability exists in the PDF parsing functionality of Infix 7.1.5. A specially crafted PDF file can cause a vulnerability resulting in potential memory corruption. An attacker can send the victim a specific PDF file to trigger this vulnerability.

Eternal Champion Exploit Analysis

Recently, a group named the ShadowBrokers published several remote server exploits targeting various protocols on older versions of Windows. In this post we are going to look at the EternalChampion exploit in detail to see what vulnerabilities it exploited, how it exploited them, and how the latest mitigations in Windows 10 break the exploit as-written.

CVE-2017-1000376

libffi requests an executable stack allowing attackers to more easily trigger arbitrary code execution by overwriting the stack. Please note that libffi is used by a number of other libraries. It was previously stated that this affects libffi version 3.2.1 but this appears to be incorrect. libffi prior to version 3.1 on 32 bit x86 systems was vulnerable, and upstream is believed to have fixed this issue in version 3.1.

CVE-2016-3107: Issue #1833: CVE-2016-3107: Node certificate containing private key stored in world-readable file - Pulp - Pulp

It was found that the private key for the node certificate was contained in a world-readable file. A local user could possibly use this flaw to gain access to the private key information in the file.

CVE-2016-8389: TALOS-2016-0214 || Cisco Talos Intelligence Group

An exploitable integer-overflow vulnerability exists within Iceni Argus. When it attempts to convert a malformed PDF to XML, it will attempt to convert each character from a font into a polygon and then attempt to rasterize these shapes. As the application attempts to iterate through the rows and initializing the polygon shape in the buffer, it will write outside of the bounds of said buffer. This can lead to code execution under the context of the account running it.
