Kwetsbaarheden verholpen in PHP

Feiten: PHP heeft twee kritieke kwetsbaarheden verholpen. De kwetsbaarheden kunnen zonder authenticatie op afstand worden misbruikt voor het uitvoeren van willekeurige code. Alle PHP-installaties die webverzoeken verwerken zijn getroffen.
Interpretaties: De kwetsbaarheid met kenmerk CVE-2026-109618 betreft geheugenbeschadiging bij de afhandeling van een Out-of-Memory-situatie. Hierdoor kunnen interne requestgegevens slechts gedeeltelijk worden geïnitialiseerd en tijdens de verwerking als geldige gegevens worden behandeld, wat kan leiden tot Remote Code Execution.
De kwetsbaarheid met kenmerk CVE-2026-109619 betreft het achterblijven van interne globale status nadat het bijbehorende geheugen is vrijgegeven. Een volgend verzoek dat door dezelfde worker wordt verwerkt, kan deze verouderde status gebruiken voordat deze opnieuw wordt geïnitialiseerd, wat eveneens kan leiden tot Remote Code Execution.
Beide kwetsbaarheden kunnen zonder authenticatie via webverzoeken worden misbruikt en kunnen leiden tot het uitvoeren van willekeurige code op de getroffen server. Het PHP-team adviseert alle gebruikers dringend om onmiddellijk te updaten. Het NCSC adviseert daarom de beveiligingsupdates met spoed toe te passen.
Oplossingen: Upgrade naar PHP 8.5.12, 8.4.27, 8.3.36 of 8.2.35. Gebruikers van Linux-distributies en LTS-versies wordt geadviseerd de door hun leverancier beschikbaar gestelde beveiligingsupdates toe te passen.
PHP 8.1 en ouder worden niet meer regulier door het PHP-project ondersteund. Voor PHP 7.4, 8.0 en 8.1 heeft het PHP-team vanwege de ernst van de kwetsbaarheden wel minimale broncodepatches beschikbaar gesteld.
Wanneer direct updaten niet mogelijk is, zijn tijdelijke mitigerende maatregelen beschikbaar voor beide kwetsbaarheden. Het PHP-team benadrukt dat deze maatregelen slechts specifieke aanvalspaden beperken en geen volledige oplossing vormen. Alleen het installeren van een beveiligingsupdate verhelpt de kwetsbaarheden volledig.
PHP heeft updates uitgebracht om deze kwetsbaarheden te verhelpen. Zie bijgevoegde referenties voor meer informatie.
