Scoring
CVSS Scores
The Common Vulnerability Scoring System is a standardized framework
for assessing the severity of vulnerabilities in software and systems.
We collect and displays CVSS scores from various sources for each CVE.
| Score | Version | Severity | Vector | Exploitability Score | Impact Score | Source |
|---|---|---|---|---|---|---|
| CVSS 3.1 | HIGH | 9a959283-ebb5-44b6-b705-dcc2bbced522 |
Solution
Patch buffer overflow vulnerabilities to prevent arbitrary code execution.
- Apply IBM service packs and PTFs for affected versions.
- Update IBM i to the latest supported release.
- Restrict access for authenticated users.
We scan GitHub repositories to detect new proof-of-concept exploits. Following list is a collection of public exploits and proof-of-concepts, which have been published on GitHub (sorted by the most recently updated).
Results are limited to the first 15 repositories due to potential performance issues.
