Compania Intel a declarat<\/a><\/noindex> referitor la remedierea a 22 de vulnerabilit\u0103\u021bi \u00een firmware-urile pl\u0103cilor de baz\u0103 server, sistemelor server \u0219i modulelor de calcul. Trei vulnerabilit\u0103\u021bi, dintre care una a fost clasificat\u0103 ca fiind critic\u0103, (CVE-2020-8708<\/a><\/noindex> \u2014 CVSS 9.6, CVE-2020-8707<\/a><\/noindex> \u2014 CVSS 8.3, CVE-2020-8706<\/a><\/noindex> \u2014 CVSS 4.7) se manifest\u0103<\/a><\/noindex> \u00een firmware-ul controlerului BMC Emulex Pilot 3, utilizat \u00een produsele Intel. Vulnerabilit\u0103\u021bile permit accesul neautentificat la consola de management la distan\u021b\u0103 (KVM), ocolirea autentific\u0103rii \u00een cazul emul\u0103rii dispozitivelor de stocare USB \u0219i provocarea unei suprasarcini de buffer la kernelul Linux utilizat \u00een BMC. <\/p>\n

Vulnerabilitatea CVE-2020-8708 permite unui atacator neautentificat, cu acces la un segment de re\u021bea local comun cu serverul vulnerabil, s\u0103 acceseze mediu de control BMC. Se observ\u0103 c\u0103 tehnica de exploatare a vulnerabilit\u0103\u021bii este foarte simpl\u0103 \u0219i fiabil\u0103, deoarece problema este cauzat\u0103 de o eroare arhitectural\u0103. Mai mult, potrivit vorbelor lor<\/a><\/noindex> cercet\u0103torului care a descoperit vulnerabilitatea, lucrul cu BMC prin exploat este mult mai convenabil dec\u00e2t utilizarea clientului Java standard. Printre echipamentele vulnerabile se men\u021bioneaz\u0103 familiile de sisteme server Intel R1000WT, R2000WT, R1000SP, LSVRP, LR1304SP, R1000WF \u0219i R2000WF, pl\u0103cile de baz\u0103 S2600WT, S2600CW, S2600KP, S2600TP, S1200SP, S2600WF, S2600ST \u0219i S2600BP, precum \u0219i modulele de calcul HNS2600KP, HNS2600TP \u0219i HNS2600BP. Vulnerabilit\u0103\u021bile au fost remediate \u00een actualizarea firmware-ului 1.59.<\/p>\n

Conform unor surse neoficiale, informa\u021biile<\/a><\/noindex> firmware-ul pentru BMC Emulex Pilot 3 a fost scris de compania AMI, prin urmare nu este exclus<\/a><\/noindex> manifestarea vulnerabilit\u0103\u021bilor \u0219i \u00een sistemele altor produc\u0103tori. Problemele sunt prezente \u00een patch-urile externe pentru kernelul Linux \u0219i \u00een procesul de management care ruleaz\u0103 \u00een spa\u021biul utilizatorului, codul acestora fiind caracterizat de cercet\u0103torul care a descoperit problema ca fiind cel mai slab cod cu care s-a confruntat.<\/p>\n

Reamintim c\u0103 BMC reprezint\u0103 un controler specializat instalat \u00een servere, av\u00e2nd propriul CPU, memorie, stocare \u0219i interfe\u021be pentru interogarea senzorilor, care ofer\u0103 o interfa\u021b\u0103 de nivel inferior pentru monitorizarea \u0219i gestionarea echipamentului serverului. Cu ajutorul BMC-ului, indiferent de sistemul de operare care ruleaz\u0103 pe server, se poate monitoriza starea senzorilor, gestiona energia, firmware-urile \u0219i discurile, organiza o \u00eenc\u0103rcare de la distan\u021b\u0103 prin re\u021bea, asigura func\u021bionarea consolei de acces la distan\u021b\u0103 etc. <\/p>\n
