The RPC API in the RSCD agent in BMC BladeLogic Server Automation (BSA) 8.2.x, 8.3.x, 8.5.x, 8.6.x, and 8.7.x on Linux and UNIX allows remote attackers to bypass authorization and reset arbitrary user passwords by sending an action packet to xmlrpc after an authorization failure.
CVE-2016-1543
Score elevated to 8.6 because EPSS predicts 72% probability of exploitation within the next 30 days (top 0.6% of all CVEs). NVD baseline CVSS 7.5 retained for reference. Confidence: see factors.
- High exploitation likelihood — EPSS 72%
No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.
