Beskrivelse:
Der er rapporteret nogle sårbarheder i Cisco Unified Communications Manager (CUCM), som kan udnyttes af ondsindede personer til at udføre et DoS (Denial of Service) eller potentielt kompromittere et sårbart system.
1) En off-by-one fejl i Certificate Trust List Provider servicen (CTLProvider.exe) kan udnyttes til at forårsage et heap-baseret buffer overflow ved at sende specielt udformede pakker til servicen (som standard port 2444/TCP).
Note: Denne sårbarhed berører ikke CUCM 3.x.
2) Et heltals-overflow i Real-Time Information Server (RIS) Data Collector servicen (RisDC.exe) kan udnyttes til at forårsage et heap-baseret buffer overflow ved at sende specielt udformede pakker til servicen (som standard port 2556/TCP).
Succesfuld udnyttelse kan muliggøre eksekvering af vilkårlig kode.
Løsning:
Installér opdaterede versioner.
Sårbarhed #1 er rettet i CUCM version 4.1(3)SR5, 4.2(3)SR2, 4.3(1)SR1 og 5.1(2).
Sårbarhed #2 er rettet i CUCM version 3.3(5)SR2b, 4.1(3)SR5, 4.2(3)SR2, 4.3(1)SR1 og 5.1(2).
