CVE-2007-5243

HIGHCVSS v2 · 9.39.3—
EchelonGraph scoreLOW confidence

This CVE was only ever scored under CVSS v2.0. NVD CVSS v2.0 base 9.3 — 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:M/Au:N/C:C/I:C/A:C. 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 40.1% exploitation probability in the next 30 days, which is reflected in EG Risk but does not lift the v2 base. Confidence: LOW.

Multiple stack-based buffer overflows in Borland InterBase LI 8.0.0.53 through 8.1.0.253, and WI 5.1.1.680 through 8.1.0.257, allow remote attackers to execute arbitrary code via (1) a long service attach request on TCP port 3050 to the (a) SVC_attach or (b) INET_connect function, (2) a long create request on TCP port 3050 to the (c) isc_create_database or (d) jrd8_create_database function, (3) a long attach request on TCP port 3050 to the (e) isc_attach_database or (f) PWD_db_aliased function, or unspecified vectors involving the (4) jrd8_attach_database or (5) expand_filename2 function.
