OpenSSL < 0.9.7a and 0.9.6 < 0.9.6i - Timing Side-Channel Attack via Incorrect Block Cipher Padding
Title source: llmExploitation Summary
EIP tracks 1 public exploit for CVE-2003-0078. PoCs published by Martin Vuagnoux.
AI-analyzed exploit summary This is a writeup describing a side-channel attack against SSL implementations, specifically targeting OpenSSL versions prior to 0.9.6i and 0.9.7a. The attack involves timing analysis to leak sensitive information, potentially leading to plaintext recovery of ciphertext.
Description
ssl3_get_record in s3_pkt.c for OpenSSL before 0.9.7a and 0.9.6 before 0.9.6i does not perform a MAC computation if an incorrect block cipher padding is used, which causes an information leak (timing discrepancy) that may make it easier to launch cryptographic attacks that rely on distinguishing between padding and MAC verification errors, possibly leading to extraction of the original plaintext, aka the "Vaudenay timing attack."
