CVE-2013-1697
HighSummary
Implementacja XrayWrapper w Mozilla Firefox przed wersją 22.0, Firefox ESR 17.x przed 17.0.7, Thunderbird przed 17.0.7 oraz Thunderbird ESR 17.x przed 17.0.7 nie ogranicza prawidłowo użycia DefaultValue dla wywołań metod. To pozwala zdalnym atakującym na wykonanie dowolnego kodu JavaScript z uprawnieniami chrome poprzez spreparowaną stronę internetową, która wywołuje zdefiniowaną przez użytkownika metodę (1) toString lub (2) valueOf.
Risk Assessment
Atakujący może wykorzystać tę podatność do uruchomienia złośliwego kodu w kontekście przeglądarki, co może prowadzić do kradzieży danych lub przejęcia kontroli nad systemem użytkownika. Organizacje powinny być świadome ryzyka związanego z używaniem nieaktualnych wersji oprogramowania.
Recommendation
Zaleca się aktualizację Mozilla Firefox, Thunderbird oraz ich wersji ESR do najnowszych wersji, aby zniwelować tę podatność. Regularne aktualizacje oprogramowania są kluczowe dla zapewnienia bezpieczeństwa systemów.

Original NVD description (English source)
The XrayWrapper implementation in Mozilla Firefox before 22.0, Firefox ESR 17.x before 17.0.7, Thunderbird before 17.0.7, and Thunderbird ESR 17.x before 17.0.7 does not properly restrict use of DefaultValue for method calls, which allows remote attackers to execute arbitrary JavaScript code with chrome privileges via a crafted web site that triggers use of a user-defined (1) toString or (2) valueOf method.
