Mismatch? CVSS, Vulnerability Management, and Organizational Risk
I’ll never forget a meeting I attended where a security engineer demanded IT remediate each of the 30,000 vulnerabilities he had discovered. I know that he wasn’t just dumping an unvetted pile of vulnerabilities on IT; he’d done his best to weed out false-positive results, other errors, and misses before presenting the findings. These were real issues, ranked using the Common Vulnerability Scoring System (CVSS). There can be no doubt that in that huge (and overwhelming) pile were some serious threats to the organization and its digital assets. The reaction…
10 Laws of Disclosure
In my 20+ years working in cyber security, I’ve reported more than 1000 vulnerabilities to a wide variety of companies, most found by our team at IOActive as well as some found by me. In reporting these vulnerabilities to many different vendors, the response (or lack thereof) I got is also very different, depending on vendor security maturity. When I think that I have seen everything related to vulnerability disclosures, I’ll have new experiences – usually bad ones – but in general, I keep seeing the same problems over and…
GE Reason S20 Industrial Managed Ethernet Switch Multiple Vulnerabilities
The S20 Ethernet Switch is a device manufactured by GE Grid Solution which is deployed in industrial environments. This device is part of ICS/SCADA architectures. Stored XSS flaws can result in a large number of possible exploitation scenarios. With most XSS flaws, the entirety of the JavaScript language is available to the malicious user.
pppd Vulnerable to Buffer Overflow Due to a Flaw in EAP Packet Processing (CVE-2020-8597)
Due to a flaw in the Extensible Authentication Protocol (EAP) packet processing in the Point-to-Point Protocol Daemon (pppd), an unauthenticated remote attacker may be able to cause a stack buffer overflow, which may allow arbitrary code execution on the target system. This vulnerability is due to an error in validating the size of the input before copying the supplied data into memory. As the validation of the data size is incorrect, arbitrary data can be copied into memory and cause memory corruption possibly leading to the execution of unwanted code.
Do You Blindly Trust LoRaWAN Networks for IoT?
Do you blindly trust that your IoT devices are being secured by the encryption methods employed by LoRaWAN? If so, you’re not alone. Long Range Wide Area Networking (LoRaWAN) is a protocol designed to allow low-power devices to communicate with Internet-connected applications over long-range wireless connections. It’s being adopted by major organizations across the world because of its promising capabilities. For example, a single gateway (antenna) can cover an entire city, hundreds of square miles. With more than 100 million LoRaWAN-connected devices in use across the globe, many cellular carriers…
LoRaWAN Networks Susceptible to Hacking: Common Cyber Security Problems, How to Detect and Prevent Them
LoRaWAN is fast becoming the most popular wireless, low-power WAN protocol. It is used around the world for smart cities, industrial IoT, smart homes, etc., with millions of devices already connected. The LoRaWAN protocol is advertised as having “built-in encryption” making it “secure by default.” As a result, users are blindly trusting LoRaWAN networks and not paying attention to cyber security; however, implementation issues and weaknesses can make these networks easy to hack. Currently, cyber security vulnerabilities in LoRaWAN networks are not well known, and there are no existing tools…
Android (AOSP) Download Provider SQL Injection in Query Sort Parameter (CVE-2019-2196)
A malicious application with the INTERNET permission granted could retrieve all entries from the Download Provider internal database, bypassing all currently implemented access control mechanisms, by exploiting an SQL injection in the sort parameter (ORDER BY clause) and appending a LIMIT clause, which allows expressions, including subqueries. The information retrieved from this provider may include potentially sensitive information such as file names, descriptions, titles, paths, URLs (which may contain sensitive parameters in the query strings), cookies, custom HTTP headers, etc., for applications such as Gmail, Google Chrome, the Google Play…
Android (AOSP) Download Provider SQL Injection in Query Selection Parameter (CVE-2019-2198)
A malicious application with the INTERNET permission granted could retrieve all entries from the Download Provider internal database, bypassing all currently implemented access control mechanisms by exploiting an SQL injection in the selection clause. The information retrieved from this provider may include potentially sensitive information such as file names, descriptions, titles, paths, URLs (that may contain sensitive parameters in the query strings), cookies, custom HTTP headers, etc., for applications such as Gmail, Google Chrome, the Google Play Store, etc.
Android (AOSP) TV Provider SQL Injection in Query Projection Parameter (CVE-2019-2211)
A malicious application without any granted permission could retrieve all entries from the TV Provider internal database, bypassing all currently implemented access control mechanisms by exploiting an SQL injection in the projection parameter. The information retrieved from this provider may include personal and potentially sensitive information about other installed applications and user preferences, habits, and activity, such as available channels and programs, watched programs, recorded programs, and titles in the “watch next” list.
Buffer Overflow, Cross-Site Scripting / Request Forgery, URI Injection, Insecure SSH Key Exchange in Antaira LMX-0800AG
(eight advisories in document) Antaira’s firmware version 3.0 for the LMX-0800AG switch (among other supported devices) is affected by a memory corruption vulnerability when processing cookies. An unauthenticated attacker could leverage the vulnerability to take full control over the switch. It is also affected by a memory corruption vulnerability when processing ioIndex GET parameter values. An attacker with valid credentials for the web interface could leverage the vulnerability to take full control of the switch. Antaira’s firmware version 3.0 for the LMX-0800AG switch (among other supported devices) is affected by…
