Multiple stack-based buffer 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 (1) a long username in an On_FC_CONNECT_FCS_LOGIN packet, and crafted (2) On_FC_CTAGLIST_FCS_CADDTAG, (3) On_FC_CTAGLIST_FCS_CDELTAG, (4) On_FC_CTAGLIST_FCS_ADDTAGMS, (5) On_FC_RFUSER_FCS_LOGIN, (6) unspecified "On_FC_BINFILE_FCS_*FILE", (7) On_FC_CGETTAG_FCS_GETTELEMETRY, (8) On_FC_CGETTAG_FCS_GETCHANNELTELEMETRY, (9) On_FC_CGETTAG_FCS_SETTELEMETRY, (10) On_FC_CGETTAG_FCS_SETCHANNELTELEMETRY, and (11) On_FC_SCRIPT_FCS_STARTPROG packets to port 910.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
