In my personal time I hunt for vulnerabilities in open and closed source software.  Below is a list of my publicly acknowledged vulnerabilities.

CVE-2019-4606 – IBM Db2 High Performance Unload is affected by 3RD PARTY – Unquoted Service Path vulnerability

IBM DB2 High Performance Unload could allow a local attacker to execute arbitrary code on the system, caused by an untrusted search path vulnerability. By using a executable file, an attacker could exploit this vulnerability to execute arbitrary code on the system.


CVE-2019-4587 – IBM® Db2® is vulnerable to privilege escalation

IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) could allow a local authenticated attacker to gain elevated privileges on the system, caused by an unquoted search path in sshd_worker.exe. By inserting arbitrary file in the path, an attacker could exploit this vulnerability to execute arbitrary code with SYSTEM privileges


CVE-PENDING – VMWare Fusion arbitrary file overwrite

VMWare Fusion v11.5.0 and earlier is vulnerable to an arbitrary file overwrite. Certain operations open a file insecurely in a world writable location which can allow a local unprivileged user the ability cause an arbitrary file to be overwritten.


CVE-2019-3466 – CVE-2019-3466 Debian / Ubuntu Privilege Escalation via pg_ctlcluster

pg_ctlcluster script didn’t drop privileges when creating socket/statistics temporary directories, which could result in local privilege escalation


CVE-2019-4523 – IBM Db2 High Performance Unload is affected by 3RD PARTY – Buffer Overflow in –credential keystore vulnerability

IBM DB2 High Performance Unload is vulnerable to a buffer overflow, caused by improper bounds checking which could allow a local attacker to execute arbitrary code on the system with root privileges.


CVE-2019-2390 – mongoDB Elevation of Privilege Vulnerability

An unprivileged user or program on Microsoft Windows which can create OpenSSL configuration files in a fixed location may cause utility programs shipped with MongoDB server versions less than 4.0.11, 3.6.14, and 3.4.22 to run attacker defined code as the user running the utility.


CVE-2019-1211 – Git for Visual Studio Elevation of Privilege Vulnerability

An elevation of privilege vulnerability exists in Git for Visual Studio when it improperly parses configuration files. An attacker who successfully exploited the vulnerability could execute code in the context of another local user.


CVE-2019-4447 – Privilege escalation in IBM DB2 HPU via loading DB2 library

IBM DB2 High Performance Unload load shared libraries from an untrusted path potentially giving low privilege user full access to root by loading a malicious shared library.


CVE-2019-4448 – Privilege escalation in IBM DB2 HPU debug binary via trusted PATH

IBM DB2 High Performance Unload debug binary is a setuid root binary which trusts the PATH environment variable. A low privileged user can execute arbitrary commands as root by altering the PATH variable to point to a user controlled location.


CVE-2019-1552 – OpenSSL Windows builds with insecure path defaults

OpenSSL has internal defaults for a directory tree where it can find a configuration file as well as certificates used for verification in TLS. This directory is most commonly referred to as OPENSSLDIR, and is configurable with the –prefix / –openssldir configuration options.

However, mingw programs are Windows programs, and as such, find
themselves looking at sub-directories of ‘C:/usr/local’, which may be
world writable, which enables untrusted users to modify OpenSSL’s
default configuration, insert CA certificates, modify (or even
replace) existing engine modules, etc.


CVE-2019-4154 – IBM® Db2® is vulnerable to buffer overflow leading to potential arbitrary code execution as root.

IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) is vulnerable to a buffer overflow, which could allow an authenticated local attacker to execute arbitrary code on the system as root.


CVE-2019-4057 – IBM® Db2® is vulnerable to privilege escalation to root via malicious use of fenced user.

CVE-2019-5443 – cURL libcurl for Windows OpenSSL engine code execution

A non-privileged user or program can put code and a config file in a known non-privileged path (under C:/usr/local/) that will make curl automatically run the code (as an openssl “engine”) on invocation. If that curl is invoked by a privileged user it can do anything it wants.

HackerOne Report: 608577


stunnel Windows stunnel Elevation of Privilege Vulnerability via malicious OpenSSL Engine loading

A low privileged user can create a openssl.cnf configuration file to load a malicious OpenSSL engine library resulting in arbitrary code execution with the full authority of as the account running stunnel. If the Stunnel TLS wrapper service is used, this will be SYSTEM.

Vendor Advisory: stunnel 5.55 released

CVE-2018-18555 – VyOS Multiple restricted shell escapes for operators

A sandbox escape issue was discovered in VyOS 1.1.8. It provides a restricted management shell for operator users to administer the device. By issuing various shell special characters with certain commands, an authenticated operator user can break out of the management shell and gain access to the underlying Linux shell. The user can then run arbitrary operating system commands with the privileges afforded by their account.


CVE-2018-18556 – VyOS Privilege escalation via sudo pppd

A privilege escalation issue was discovered in VyOS 1.1.8. The default configuration also allows operator users to execute the pppd binary with elevated (sudo) permissions. Certain input parameters are not properly validated. A malicious operator user can run the binary with elevated permissions and leverage its improper input validation condition to spawn an attacker-controlled shell with root privileges. View the write-up and PoC CVE-2018-18556.sh.


CVE-2018-1710 – Buffer overflow in IBM® Db2® tool db2licm

IBM DB2 for Linux, UNIX and Windows (includes DB2 Connect Server) tool db2licm is affected by buffer overflow vulnerability that can potentially result in arbitrary code execution.


CVE-2018-5546 – BIG-IP APM client for Linux and macOS vulnerability

The svpn and policyserver components of the F5 BIG-IP APM client prior to version 7.1.7.1 for Linux and macOS runs as a privileged process and can allow an unprivileged user to get ownership of files owned by root on the local client host.


CVE-2018-2939 – Oracle DBMS arbitrary file overwrite vulnerabilities

Vulnerability in the Core RDBMS component of Oracle Database Server. Supported versions that are affected are 11.2.0.4, 12.1.0.2, 12.2.0.1, 18.1 and 18.2. Easily exploitable vulnerability allows low privileged attacker having Local Logon privilege with logon to the infrastructure where Core RDBMS executes to compromise Core RDBMS. While the vulnerability is in Core RDBMS, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Core RDBMS accessible data and unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Core RDBMS.


CVE-2018-5529 – F5 BIG-IP APM client for Linux and Mac OS X vulnerability

The svpn component of the BIG-IP APM client for Linux and Mac OS X runs as a privileged process and can allow an unprivileged user to assume super-user privileges on the local client host.


CVE-2018-1458 – Multiple untrusted search path vulnerabilities in the IBM® Db2® DAS component on Windows

Multiple untrusted search path vulnerabilities in the Db2 Administration Server (DAS) component of Db2 on Windows could allow a local user to execute arbitrary code.


CVE-2018-1487 – Privilege escalation in IBM® Db2® via loading libraries from untrusted path

Db2 loads shared libraries from an untrusted path potentially giving low privilege user full access to the DB2 instance account by loading a malicious shared library. All instance owner executables that run with elevated privileges (setuid) are affected. Root setuid executables are not affected. The implication is that if the customer has implemented their own applications which run with elevated privileges (setuid) those are affected as well, and it is up to the customer to ensure that the DB2INSTANCE environment variable is correctly set to the Db2 instance owner, and not modified by a malicious user.
