Pentru a efectua atacul, nu este necesar\u0103 autentificarea pe server.<\/p>\n

    <\/p>\n
  1. CVE-2023-42115<\/a> \u2014 permite ob\u021binerea de date proprii dincolo de limita tamponului dedicat. Este cauzat\u0103 de o eroare de validare a datelor de intrare \u00een serviciul SMTP.<\/li>\n

  3. CVE-2023-42117<\/a> \u2014 este, de asemenea, cauzat\u0103 de lipsa verific\u0103rii datelor de intrare pe portul 25 al serviciului SMTP.<\/li>\n<\/ol>\n

    Vulnerabilit\u0103\u021bile sunt catalogate ca 0-day, ceea ce \u00eenseamn\u0103 c\u0103 nu sunt remediate, de\u0219i potrivit ZDI, dezvoltatorii Exim au fost deja avertiza\u021bi despre existen\u021ba lor.

    Ca m\u0103sur\u0103 de protec\u021bie \u00eempotriva acestor vulnerabilit\u0103\u021bi, \u00een prezent se recomand\u0103 restric\u021bionarea accesului la SMTP pe portul 25.<\/p>\n
