CVE-2024-47921: Smadar SPS Cryptographic Algorithm Vulnerability

CVE-2024-47921 Overview

CVE-2024-47921 identifies a cryptographic weakness in Smadar SPS classified under [CWE-327]: Use of a Broken or Risky Cryptographic Algorithm. The flaw stems from reliance on outdated or insecure cryptographic primitives that fail to protect the confidentiality and integrity of data processed by the affected product. An attacker with local access can leverage the weakness to compromise sensitive information, tamper with protected data, and disrupt availability. The vulnerability was published to the National Vulnerability Database (NVD) on December 30, 2024, and is tracked by Israeli Government CVE advisories.

Critical Impact

Technical Details for CVE-2024-47921

Vulnerability Analysis

The vulnerability originates in the Smadar SPS product's use of a cryptographic algorithm considered broken or risky by modern standards. Algorithms flagged under [CWE-327] typically include obsolete ciphers such as DES, RC4, or MD5, or misuse of stronger primitives without secure modes or key management. When such algorithms protect authentication tokens, stored secrets, or transported data, the guarantees they were designed to provide no longer hold.

An attacker with local access to the system running Smadar SPS can target the weak cryptographic routines to recover plaintext from ciphertext, forge integrity values, or replay authenticated messages. The advisory indicates that a successful attack does not require prior authentication or user interaction, which broadens the population of potential attackers on shared or multi-user hosts.

Because the weakness sits at the algorithm layer, downstream components that trust the cryptographic output inherit the risk. This means credentials, configuration secrets, or protected control data handled by Smadar SPS can be manipulated once the underlying primitive is defeated.

Root Cause

The root cause is the selection or configuration of a cryptographic algorithm that no longer meets accepted security requirements. This may involve short key lengths, deprecated hash functions, insecure cipher modes, or predictable initialization values. The advisory does not specify the exact primitive, but the [CWE-327] classification confirms the failure category.

Attack Vector

Exploitation requires local access to the host where Smadar SPS is deployed. Once positioned locally, an attacker can interact with the cryptographic interfaces, harvest ciphertext or hashes protected by the weak algorithm, and apply known cryptanalytic techniques to recover secrets or forge data. The CVSS vector indicates no privileges and no user interaction are required, so any local user context can be sufficient to initiate the attack. Refer to the Israeli Government CVE Advisories for further technical context.

No public exploit or proof-of-concept code has been published for this vulnerability at the time of writing.

Detection Methods for CVE-2024-47921

Indicators of Compromise

Unexpected access to Smadar SPS cryptographic key stores, configuration files, or credential caches by local user accounts.
Presence of cryptanalysis tools, hash-cracking utilities, or scripts referencing legacy algorithms (DES, RC4, MD5, SHA-1) on hosts running Smadar SPS.
Anomalous process activity spawning from or interacting with Smadar SPS binaries and libraries.

Detection Strategies

Inventory cryptographic algorithms in use by Smadar SPS through static analysis of configuration files and binaries, and flag any deprecated primitives.
Correlate local logon events with subsequent access to Smadar SPS data directories to identify unauthorized interaction with protected material.
Monitor for offline copies of Smadar SPS-protected files being moved to attacker-controlled paths or external media.

Monitoring Recommendations

Enable process and file access auditing on directories owned by Smadar SPS to capture read operations against key and secret material.
Alert on execution of cryptography-related command-line tools (openssl, hashcat, john) by non-administrator users on systems hosting Smadar SPS.
Track integrity of Smadar SPS binaries and configuration files to detect tampering that could downgrade cryptographic settings further.

How to Mitigate CVE-2024-47921

Immediate Actions Required

Contact Smadar and confirm the fixed version or patch level that remediates CVE-2024-47921, then plan an expedited upgrade.
Restrict local access to systems running Smadar SPS to the minimum set of administrative users required for operation.
Rotate any credentials, keys, or tokens that were previously protected by the affected cryptographic implementation.

Patch Information

The advisory referenced by the Israeli Government CVE Advisories portal is the authoritative source for vendor remediation guidance for Smadar SPS. Administrators should apply the vendor-supplied update that replaces the broken algorithm with a modern primitive such as AES-GCM with proper key management, and SHA-256 or stronger for hashing.

Workarounds

Enforce host-level access controls so that only trusted operators can reach Smadar SPS interfaces and stored data.
Where the product allows algorithm configuration, disable deprecated ciphers and hashes and enable only current, approved primitives.
Encrypt the underlying storage volume that holds Smadar SPS data at the operating system layer to add defense in depth until the vendor patch is applied.

bash

# Configuration example: restrict local access and audit cryptographic material
# Limit directory access to the Smadar SPS service account
chown -R smadar:smadar /opt/smadar/sps
chmod 700 /opt/smadar/sps

# Enable Linux audit rules for key and config directories
auditctl -w /opt/smadar/sps/keys -p rwxa -k smadar_keys
auditctl -w /opt/smadar/sps/conf -p wa -k smadar_conf
