Beskrivelse:
Aliaksandr Hartsuyeu har identificeret en sårbarhed i ACal, som kan udnyttes af ondsindede personer til at omgå bestemte sikkerhedsrestriktioner og kompromittere et sårbart system.

Sårbarheden skyldes en usikker brugergodkendelsesprocess. Dette kan udnyttes til at tilgå den administrative sektion ved at sætte cookie parameteren "ACalAuthenticate" til "inside".

Dette kan yderligere udnyttes til at indsætte og eksekvere vilkårlig PHP kode ved at manipulere header og footer filer.

Sårbarheden er bekræftet i version 2.2.5. Andre versioner er muligvis oså berørte.

Løsning:
Opdatér til version 2.2.6.
