Summary

CVE-2024-57854 is a critical-severity PRNG (CWE-338) vulnerability in Dougdude Net\. Its CVSS base score is 9.1 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Forge Web Credentials (T1606); ranked at the 34th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SC-13 (Cryptographic Protection) and SA-8 (Security and Privacy Engineering Principles) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

CVE-2024-57854 is a vulnerability in Net::NSCA::Client versions through 0.009002 for Perl, stemming from the use of a poor random number generator for initialization vectors in initial packets. Starting with version v0.003, the module switched from Crypt::Random to Data::Rand::Obscure, which depends on Perl's built-in rand() function that is not cryptographically secure. This issue falls under CWE-338 (Use of Cryptographically Weak Random Number Generator) and carries a CVSS v3.1 base score of 9.1 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N).

The vulnerability enables network-based exploitation with low attack complexity, requiring no privileges, user interaction, or scope changes. Attackers can achieve high impacts on confidentiality and integrity, potentially by predicting or forging initialization vectors in NSCA packets sent by the client.

Mitigation details appear in available references, including a patch in pull request 2 at https://patch-diff.githubusercontent.com/raw/dougwilson/perl5-net-nsca-client/pull/2.patch and an announcement on the oss-security mailing list at http://www.openwall.com/lists/oss-security/2026/03/05/1. The vulnerable code is visible in the source at https://metacpan.org/release/DOUGDUDE/Net-NSCA-Client-0.009002/source/lib/Net/NSCA/Client/InitialPacket.pm#L119; practitioners should apply the patch or upgrade to a fixed version.
