CVE-2011-1564

Status: ModifiedHigh (10)—

Multiple integer overflows in the HMI application in DATAC RealFlex RealWin 2.1 (Build 6.1.10.10) and earlier allow remote attackers to execute arbitrary code via crafted (1) On_FC_MISC_FCS_MSGBROADCAST and (2) On_FC_MISC_FCS_MSGSEND packets, which trigger a heap-based buffer overflow.

CVSS

Exploitation probability (EPSS)

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).
