Full Report
As many as 768 vulnerabilities with designated CVE identifiers were reported as exploited in the wild in 2024, up from 639 CVEs in 2023, registering a 20% increase year-over-year. Describing 2024 as "another banner year for threat actors targeting the exploitation of vulnerabilities," VulnCheck said 23.6% of known exploited vulnerabilities (KEV) were known to be weaponized either on or before
Analysis Summary
This is a summary based on the provided article, which reports on aggregate vulnerability exploitation trends for 2024, rather than detailing a single specific vulnerability. Therefore, specific details like CVE IDs, severity scores, affected products, and patches are generalized based on mentioned high-profile examples and aggregate statistics.
# Vulnerability: Aggregate Exploited Vulnerabilities in 2024
## CVE Details
- CVE ID: N/A (Reporting on 768 distinct CVEs exploited in the wild in 2024)
- CVSS Score: Varies widely due to aggregation
- CWE: Varies widely due to aggregation
## Affected Systems
- Products: Apache, Atlassian, Barracuda, Citrix, Cisco, Fortinet, Microsoft, Progress, PaperCut, and Zoho (These vendors are noted to have systems susceptible to the top routinely exploited vulnerabilities).
- Versions: Not specified for all 768 CVEs.
- Configurations: The article notes that roughly 400,000 internet-accessible systems are potentially susceptible to attacks stemming from the exploitation of 15 security shortcomings in the listed technologies.
## Vulnerability Description
The article reports a 20% increase in reported exploited vulnerabilities in the wild in 2024 (768 CVEs) compared to 2023 (639 CVEs). A significant portion (23.6%) of these exploited vulnerabilities were weaponized on or before the day their CVE was publicly disclosed. The Log4j vulnerability, **CVE-2021-44228**, remains highly significant, associated with 31 named threat actors.
## Exploitation
- Status: **Exploited in the wild**. 1% of all published CVEs in 2024 were reported publicly as exploited.
- Complexity: Mixed, but high weaponization speed suggests many have low complexity.
- Attack Vector: Varies, but includes vulnerabilities allowing network access (implied by targeting internet-facing systems).
## Impact
Impact is generalized across the 768 exploited CVEs, affecting:
- Confidentiality: High across various exploited systems.
- Integrity: High across various exploited systems.
- Availability: High across various exploited systems.
## Remediation
### Patches
Specific patches are not detailed for all 768 CVEs. However, the need for robust patch management is explicitly stated. (The Log4j exploit example points to the necessity of patching known flaws).
### Workarounds
- Enhance visibility into potential risks.
- Leverage robust threat intelligence.
- Implement mitigating controls such as minimizing internet-facing exposure of vulnerable devices wherever possible.
## Detection
- Indicators of Compromise: Not specified, as this is an aggregate report. However, threat actors are actively targeting newly disclosed vulnerabilities very rapidly.
- Detection methods and tools: Organizations are advised to use robust threat intelligence to monitor for active exploitation of disclosed CVEs.
