Post-Quantum Security of Block Cipher Constructions

Block ciphers are versatile cryptographic ingredients that are used in a wide range of applications ranging from secure Internet communications to disk encryption. While post-quantum security of public-key cryptography has received significant attention, the case of symmetric-key cryptography and...

GHSA-XWCQ-PM8M-C4VF crypto-js PBKDF2 1,000 times weaker than specified in 1993 and 1.3M times weaker than current standard

Impact Summary Crypto-js PBKDF2 is 1,000 times weaker than originally specified in 1993, and at least 1,300,000 times weaker than current industry standardOWASP PBKDF2 Cheatsheet. This is because it both 1 defaults to SHA1SHA1 wiki, a cryptographic hash algorithm considered insecure since at leas...

SHA1 Hashing Algorithm vulnerable to Length Extension Attack

Lines of code Vulnerability details Impact The implementation of the SHA1 hashing algorithm in the code has a significant impact as it is vulnerable to the length extension attack. This attack enables us to create a new hash for an extended message without altering the existing hash, even though ...

computeAddress does not follow the standard procedure to compute the address. The contract can not create pool for some pairs due to hash collision

Lines of code Vulnerability details Impact Poor source of randomness, an attacker can easily decipher the computed address. The contract can be easily tricked. This can cause hash collision, due to this, for some pairs, the contract can not create pool. Proof of Concept AlgebraFactory.solL123 : T...

FortiMail - Salted Digest vulnerable to length extension attacks

A missing cryptographic step in the implementation of the hash digest algorithm in FortiMail may allow an unauthenticated attacker to tamper with signed URLs by appending further data which allows bypass of signature verification...

Zomato: Length extension attack leading to HTML injection

At the profile setting page where I can set my personal website I found this url: https://www.zomato.com/redirect?u=xxx&t=yyy Where xxx is the url that we can control and yyy is the hash. Through out blackbox testing I find out that if md5somescret + url == t then the redirect is allowed. This is...
