Summary
Crypt::PBKDF2 versions before 0.261630 for Perl have a weak default algorithm and number of iterations. The default algorithm is HMAC-SHA1, which should only be used for legacy systems.
Risk Assessment
The weak algorithm and low number of iterations may lead to easier password cracking, posing a risk to the organization's data security.
Recommendation
It is recommended to upgrade to a newer version of Crypt::PBKDF2 and increase the number of iterations to at least 220,000 to enhance password security.
Other vulnerabilities in Crypt::PBKDF2
See all- CVE-2017-20240Medium
Crypt::PBKDF2 versions before 0.261630 for Perl are vulnerable to timing attacks. The use of Perl's built-in eq comparison may allow an attacker to guess the underlying derived key by analyzing timing discrepancies.
- CVE-2026-9638High
Crypt::PBKDF2 versions before 0.261630 for Perl generate insecure random values for salts. They use the built-in rand function, which is predictable and unsuitable for cryptography.
Original NVD description (English source)
Crypt::PBKDF2 versions before 0.261630 for Perl have a weak default algorithm and number of iterations. The default algorithm is HMAC-SHA1, which should only be used for legacy systems. These versions default to using 1000 iterations. Depending on the chosen algorithm, 220,000 to 1,400,000 iterations should be used.
