Status: ModifiedHigh (8.8)—
Gocloud S2A_WL 4.2.7.16471, S2A 4.2.7.17278, S2A 4.3.0.15815, S2A 4.3.0.17193, S3A K2P MTK 4.2.7.16528, S3A 4.3.0.16572, and ISP3000 4.3.0.17190 devices allows remote attackers to execute arbitrary OS commands via shell metacharacters in a ping operation, as demonstrated by the cgi-bin/webui/admin/tools/app_ping/diag_ping/; substring.
CVSS
- Version: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
- Base score: 8.8
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 2.85%
- Percentile among all scored CVEs: 86
- Score date: 10/14/2026
EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
