On June 11, 2024, a Microsoft Engineer posted information about a crash that inadvertently leaked internal data related to PlayReady and Warbird libraries.
0f71fa63d28b5ccf3a78398618e02286375e172ff1d63d1f7602e519ca576dbeThe Security Explorations team has come up with two attack scenarios that make it possible to extract private ECC keys used by a PlayReady client (Windows SW DRM scenario) for the communication with a license server and identity purposes. Proof of concept included.
c2dc2010ee36581d568d891c24ac2a0dfd8b8a87de8de3d72f1072bb1e38964aSystemd-run/run0 allocates user-owned ptys and attaches the slave to high privilege programs without changing ownership or locking the pty slave.
15c380418f4bc926342668506e97514b64da3e44af7c265140bf54c41a2ae6b3The Microsoft PlayReady toolkit assists with fake client device identity generation, acquisition of license and content keys for encrypted content, and much more. It demonstrates weak content protection in the environment of CANAL+. The proof of concept exploit 3 year old vulnerabilities in CANAL+ STB devices, which make it possible to gain code execution access to target STB devices over an IP network.
79dab3a7323f19a26d78f497deb3ea0052f2376b984ec830648a755230a60801There is yet another attack possible against Protected Media Path process beyond the one involving two global XOR keys. The new attack may also result in the extraction of a plaintext content key value.
624d62ae93c4eb9ee488a2e78ae15c8b8b941fc79346a6f1e3994060ab88fc9bMicrosoft PlayReady suffers from issues that can lead to disclosure of plaintext keys used to protect DRM'ed content.
28a472f25d72b716bdb5a514be5776a5e12b397df68219d437bd1398ff26e123This is an extension of research on the original findings of CVE-2020-15858 in Telit Cinterion IoT devices. Numerous issues have been discovered including path traversal, Java privilege elevation, AT commands whitelist / blacklist bypass, a heap overflow in fragmented SMS, and more.
abb8c4529f9d5d619b36098b1423bf2e497fc0bebd5da0e83e1d5c9a49803636Security Explorations conducted a security analysis of Microsoft Play Ready content protection technology in the environment of the CANAL+ SAT TV provider. As a result, complete access to movie assets and content keys available in the CANAL+ VOD library could be gained with the use of a fake client device identity. Microsoft and CANAL+ have seemingly decided to ignore this large laundry list of failures.
ae147b5df942976857f81fb745ba330474556562626f4e5abf76e56fe99dca24Security Explorations has discovered multiple security vulnerabilities in the reference implementation of Java Card technology from Oracle used in financial, government, transportation and telecommunication sectors among others. As for the impact, the vulnerabilities found make it possible to break memory safety of the underlying Java Card VM. As a result, full access to smartcard memory could be achieved, applet firewall could be broken or native code execution could be gained. This archive contains the proof of concept code that demonstrates these vulnerabilities which were originally made public in March of 2019.

01bc25f8f8df246c49b97afca9f4177773fc93680f8d029f118b41c573555d1fIn their original report, Security Explorations indicated that Issue 42 in SE-2014-02 had its origin in klassItable::initialize_itable_for_interface method's implementation of Java SE 7 HotSpot VM. They have recently learned that their initial analysis regarding the root cause of Issue 42 was incorrect. This report contains more detailed information about the actual cause of Issue 42, the reasoning that has mislead them into concluding it was caused by an improper initialization of non-public interface method slots and some additional findings regarding this issue.
