CVE-2005-2127

HIGHCVSS v2 · 7.57.5—
EchelonGraph scoreLOW confidence

This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 7.5 — v2 rates that HIGH (v2 bands: LOW 0.0–3.9 / MEDIUM 4.0–6.9 / HIGH 7.0–10.0; v2 has no CRITICAL band). Vector AV:N/AC:L/Au:N/C:P/I:P/A:P. CVSS v2 is an older, coarser metric than v3.1/v4.0 (no Scope, no User Interaction, no Attack Requirements), so it is not directly comparable to a v3 or v4 score. NVD has never re-scored this record under v3. EPSS predicts 63.7% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

Microsoft Internet Explorer 5.01, 5.5, and 6 allows remote attackers to cause a denial of service (application crash) and possibly execute arbitrary code via a web page with embedded CLSIDs that reference certain COM objects that are not intended for use within Internet Explorer, as originally demonstrated using the (1) DDS Library Shape Control (Msdds.dll) COM object, and other objects including (2) Blnmgrps.dll, (3) Ciodm.dll, (4) Comsvcs.dll, (5) Danim.dll, (6) Htmlmarq.ocx, (7) Mdt2dd.dll (as demonstrated using a heap corruption attack with uninitialized memory), (8) Mdt2qd.dll, (9) Mpg4ds32.ax, (10) Msadds32.ax, (11) Msb1esen.dll, (12) Msb1fren.dll, (13) Msb1geen.dll, (14) Msdtctm.dll, (15) Mshtml.dll, (16) Msoeacct.dll, (17) Msosvfbr.dll, (18) Mswcrun.dll, (19) Netshell.dll, (20) Ole2disp.dll, (21) Outllib.dll, (22) Psisdecd.dll, (23) Qdvd.dll, (24) Repodbc.dll, (25) Shdocvw.dll, (26) Shell32.dll, (27) Soa.dll, (28) Srchui.dll, (29) Stobject.dll, (30) Vdt70.dll, (31) Vmhelper.dll, and (32) Wbemads.dll, aka a variant of the "COM Object Instantiation Memory Corruption vulnerability."
