CVE-2020-35221

The hashing algorithm implemented for NSDP password authentication on NETGEAR JGS516PE/GS116Ev2 v2.6.0.43 devices was found to be insecure, allowing attackers with access to a network capture to quickly generate multiple collisions to generate valid passwords, or infer some parts of the original...

Properties of secure hash functions

The news of NIST and their SHA-3 algorithm competition and a recent lunch and learn at Denim Group reminded me of the Cryptographic lectures I gave at UTSA. One of the hardest concepts my students had grasping was secure cryptographic hash functions, partially because of the number theory, but al...

dnsmasq: loose query name check in reply_query() makes forging replies easier for an off-path attacker

A flaw was found in dnsmasq. When getting a reply from a forwarded query, dnsmasq checks in forward.c:replyquery, which is the forwarded query that matches the reply, by only using a weak hash of the query name. Due to the weak hash CRC32 when dnsmasq is compiled without DNSSEC, SHA-1 when it is...

MISSIONS — The Next Level of Interactive Developer Security Training

If organizations want to get serious about software security, they need to empower their engineers to play a defensive role against cyberattacks as they craft their code. The problem is, developers haven't had the most inspiring introduction to security training over the years, and anything that...

Namespace Collision

sqlite is vulnerable to namespace collision vulnerability. The vulnerability is possible because sqlite allows a virtual table to be renamed to the name of one of its shadow tables, related to alter.c and build.c...

Hash Collision

Bouncy Castle is vulnerable to hash collision attacks. The library keystore files uses a HMAC hash that is only 16 bits long, allowing a malicious user to retrieve the password used for keystore integrity verification checks. This vulnerability only affects users of the BKS-V1 keystore format,...
