Vulnerabilities Found With
A selection of open-source code vulnerabilities we discovered in customer projects.
Next to our enterprise testing platform, we maintain Jazzer, an open-source security testing solution for Java and other JVM-based languages. With the help of Jazzer, and our testing platform, hundreds of security issues and code vulnerabilities have been found in log4j, OpenJDK, and many other open-source projects.
Sucicata is an open-source threat detection engine capable of real-time intrusion detection (IDS). Even though Sucicata used fuzzing with AFL extensively, our vulnerability researchers were able to find 12 more critical code vulnerabilities (e.g. data corruptions, remote code executions, and many other unwanted program behaviors).
German COVID-19 Tracing
The Swiss/German COVID-19 tracing app was downloaded more than 25 Million times. Testing it for security vulnerabilities played an important role in ensuring public trust and increasing compliance. With CI Fuzz, our developers found 2 code vulnerabilities in the German version (#163 and #164), and 9 vulnerabilities in the Swiss version of the app.
OWASP's JSON Sanitizer transforms JSON-like input into valid and fully embeddable JSON. It is an Open Source sanitizer with over 200 dependencies. With CI Fuzz, our developers found two critical code vulnerabilities in this project, that would have exposed it to XML/HTML injections. (CVE-2021-23899 and CVE-2021-23900).
LibHTP is used to securely parse HTTP protocols and the related bits and pieces. Using CI Fuzz, our developers found a critical code vulnerability in LibHTP, that remote attackers could have exploited for a buffer over-read (CVE-2018-10243).
Audi is one of the leading innovators worldwide when it comes to making automotive software more secure. With CI Fuzz, our developers managed to fix an exploitable heap buffer overflow in Audi's software.
DLR COBS Encoder
The DLR is the federal german space research center, which focuses its research on energy, space, transport, and security technology. With CI Fuzz, our developers were able to find a heap-buffer overread in one of the DLR's COBS encoder.
CppCMS is a free, Open Source framework for web application development in C++, especially adept at handling extremely high loads. With CI Fuzz, our security researchers managed to find a critical code vulnerability (CVE-2018-11367) within the project.
GnuPG Made Easy or simply GPGME is a library that makes GnuPG access easier for applications. CI Fuzz enabled our developers to find 7 code vulnerabilities in GPGME that would have led to severe usability issues.
Jsoup is an open-source Java library used for extracting data from HTML and manipulating HTML outputs. It can also be used to parse and build XML. With Jazzer, we found over 19 bugs (CVE-2021-37714) in jsoup. Eight of them are potentially critical for the availability of web applications using jsoup.
The Apache PDFBox library is an open-source Java tool for working with PDF documents. It allows the creation of new PDF documents, manipulation of existing documents, and the ability to extract content from documents. Our fuzzers were able to find an Infinite Loop (CVE-2021-27807) and an OutOfMemory-Exception (CVE-2021-27906).
Fastjson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object. Our tests showed that this application was throwing a number of undeclared exemptions.
Json-smart is a performance focused, JSON processor lib. The application (json-smart-v1, json-smart-v2) threw uncaught exceptions. When uncaught, they may have caused programs using the library to crash or expose sensitive information. (CVE-2021-27568)
Protocol Buffers are Google's language-neutral and platform-neutral, extensible mechanism for serializing structured data. An issue in protobuf allowed malicious payload to occupy the parser for several minutes, causing frequent, repeated pauses (CVE-2021-22569).
Faster XML Jackson is a high-performance JSON processor for Java. Its developers extol the combination of fast, correct, lightweight, and ergonomic attributes of the library in which we found 2 undeclared exceptions.
The library can currently decode greyscale and RGB images (8, 16 or 32 bits). It supports LZW compression and images with an additional alpha channel. Due to our fuzzers the maintainers were able to fix an IndexOutOfBoundError, in version 2.0.3.
RE2 is a regular expression engine that runs in time linear in the size of the input. RE2/J is a port of RE2 to pure Java, where users were able to find and fix a NullPointerExeption due to our Java Fuzzer.
Gson is a Java library that can be used to convert Java Objects into their JSON representation. It can also be used to convert a JSON string to an equivalent Java object, where Jazzer found an ArrayIndeyOutOfBounds.
Fuzz Your Software With Code Intelligence
Fuzzing is the most effective approach to automatically find and fix bugs and vulnerabilities in your software.
Companies like Google already find 80% of their bugs completely automated.
How Other Companies Improved Their Security Testing
With Code Intelligence
CI Fuzz enabled Telekom's security testing experts to complete projects much faster and to increase productivity in an easy way.
Continental managed to test a large safety module with 18,000 lines of code (LoC) within only one week.
sodge IT team has implemented automated security testing in their supply chain and thus detected and fixed 3 critical vulnerabilities (CVEs).
