Korrigerande versioner av webbramverket Django 4.0.6 och 3.2.14 har publicerats, d\u00e4r en s\u00e5rbarhet (CVE-2022-34265) \u00e5tg\u00e4rdats, vilket potentiellt kan m\u00f6jligg\u00f6ra injektion av egen SQL-kod. Problemet p\u00e5verkar applikationer som anv\u00e4nder okontrollerade externa data i parametrarna kind och lookup_name, som \u00f6verf\u00f6rs till funktionerna Trunc(kind) och Extract(lookup_name). Program som endast till\u00e5ter verifierade data i v\u00e4rdena lookup_name och kind p\u00e5verkas inte av s\u00e5rbarheten. <\/p>\n

Problemet blockerades genom att f\u00f6rbjuda anv\u00e4ndning av tecken som inte \u00e4r bokst\u00e4ver, siffror, \u00ab-\u00bb, \u00ab_\u00bb, \u00ab(\u00bb och \u00ab)\u00bb i argumenten f\u00f6r funktionerna Extract och Trunc. Tidigare togs inte enkla citationstecken bort fr\u00e5n de \u00f6verf\u00f6rda v\u00e4rdena, vilket m\u00f6jliggjorde att SQL-konstruktioner kunde utf\u00f6ras genom att \u00f6verf\u00f6ra v\u00e4rden av typen \u00abday\u2019 FROM start_datetime)) OR 1=1;\u2014\u00bb och \u00abyear\u2019, start_datetime)) OR 1=1;\u2014\u00bb. I n\u00e4sta version 4.1 planeras ytterligare f\u00f6rst\u00e4rkningar av skyddet f\u00f6r metoderna f\u00f6r extraktion och avkortning av datum, men \u00e4ndringarna i API:t kommer att leda till bristande kompatibilitet med externa backend-l\u00f6sningar f\u00f6r databasarbete.
