Windows Notepad App Remote Code Execution vulnerability inoshandisa kusasimba mumananiso eNotepad mamwe mafomati uye inobata kugoverwa kwendangariro panguva yekupa zvinyorwa.

Pamusoro payo, chikamu ichi chekusagadzikana chinowanzo sanganisira buffer kufashukira kana memory uwori kukanganisa inokonzeresa kana Notepad ichigadzira faira rakarongeka. Kana mushandisi avhura gwaro rakagadzirwa — rinowanzovanza serisingakuvadzi .txt kana log file - shellcode yeanorwisa inoteedzera mukati mechikamu chemushandisi iyezvino. Nekuda kwekuti Notepad inomhanya nemvumo dzemushandisi apinda, munhu anorwisa anogona kuwana kutonga kuzere kwekodzero yekuwana account yeakaundi iyoyo, kusanganisira kuverenga/kunyora kuwana mafaera ane hanya uye zviwanikwa zvenetiweki.

Microsoft yakagadzirisa akawanda Notepad-ane chekuita nezvekuchengetedza kuraira mumakore achangopfuura kuburikidza nePatch Chipiri kutenderera, nekusagadzikana kwakanyorwa pasi peCVEs kunobata Windows 10, Windows 11, uye Windows Server editions. Muchina wacho unopindirana: kutadza kwekugadzirisa pfungwa kunogadzira mamiriro ezvinhu anogoneka kupfuura kuchengetedzwa kwendangariro.

Iyo Attack Vector Inoshanda Sei mune Chaiyo-Nyika Mamiriro?

Kunzwisisa cheni yekurwisa kunobatsira masangano kuvaka dziviriro inoshanda. Mamiriro ezvinhu ekushandiswa anotevera anoteedzera kutevedzana:

• Delivery: Murwi anogadzira faira rakashata uye anoriparadzira kuburikidza neemail ye phishing, zvinokuvadza zvekudhaunirodha zvinongedzo, madhiraivha etiweki akagoveranwa, kana masevhisi ekuchengetedza makore akanganisa.
• Kuuraya: Munhu wacho anobaya kaviri faira, iro rinovhura muNotepad nekusagadzika nekuda kweWindows file association settings ye .txt, .log, nezvimwe zviwedzerwa.
• Kushandisa Memory: Injini yeParsing yeNotepad inosangana nedata isina kurongeka, zvichikonzera murwi kana kuti stack kufashama iyo inodarika mapoinzi endangariro akakosha ane maitiro anodzorwa neanorwisa.
• Shellcode execution: Kudzora kuyerera kunoendeswa kune yakamisikidzwa payload, iyo inogona kudhawunirodha imwe malware, kumisa kushingirira, kuburitsa data, kana kufamba nedivi panetiweki.
• Kukwidziridzwa kwekodzero (optional): Kana zvikasanganiswa nerubatsiro rwechipiri rwenzvimbo, ari kurova anogona kusimuka kubva pamushandisi akajairwa kuenda kuSYSTEM-level yekuwana.

Chii chinoita kuti izvi zvive nengozi zvakanyanya kuvimba nevashandisi vanoisa muNotepad. Kusiyana nemafaira anogona kutevedzerwa, magwaro akajeka haawanzo kuongororwa nevashandi vane hanya nekuchengetedza, zvichiita kuti kufambisa kwefaira kwakagadzirwa nemagariro kushande zvakanyanya.

Key Insight: Kusagadzikana kwakanyanya hakuwanzo kuwanikwa mumashandisirwo akaomarara, akatarisana neinternet - kazhinji anogara mumaturusi akavimbika, emazuva ese ayo masangano asina kumbobvira aona sekutyisidzira. Windows Notepad muenzaniso webhuku wekuti fungidziro dzenhaka nezve "yakachengeteka" software dzinogadzira mikana yemazuva ano yekurwisa.

Ndedzipi Njodzi Dzekuenzanisa Munzvimbo Dzakasiyana dzeWindows?

Kuoma kwekusagadzikana uku kunosiyana zvichienderana neWindows nharaunda, gadziriro yemushandisi, uye chigamba chekutarisira. Bhizinesi nharaunda dzinomhanya Windows 11 neazvino anowedzeredzwa zvigadziriso uye Microsoft Defender yakagadziridzwa mu block mode kumeso kwakaderedzwa zvakanyanya zvichienzaniswa nemasangano ari kuita echikuru, asina kurongeka Windows 10 kana Windows Server zviitiko.

On Windows 11, Microsoft yakavakazve Notepad ine yemazuva ano application kurongedza, ichimhanyisa sejecha reMicrosoft Store application ine AppContainer yekuzviparadzanisa nevamwe mune mamwe magadzirirwo. Shanduko yekuvaka iyi inopa kudzikisira zvine musoro - kunyangwe RCE ikawanikwa, nzvimbo yeanorwisa inomanikidzwa nemuganho weAppContainer. Zvakadaro, iyi sandboxing haishandiswe pasi rese Windows 11 magadzirirwo, uye Windows 10 nharaunda hadzigamuchire dziviriro yakadaro nekukasira.

Masangano akadzima otomatiki Windows Updates - inokatyamadza gadziriso inowanzoitika munzvimbo dzinoshandisa legacy software - dzinoramba dziri pachena kwenguva refu mushure mekunge Microsoft yaburitsa zvigamba. Ngozi inowanda munzvimbo umo vashandisi vanogaro shanda nekodzero dzemaneja wenzvimbo, chigadziriso chinotyora musimboti werubatsiro rudiki asi chichienderera mberi mumabhizinesi madiki nepakati.

Ndeapi Matanho Anofanira Kutorwa Nemabhizinesi Kuderedza Kusagadzikana Uku?

Kudzikamisa kunoshanda kunoda nzira yakasarudzika inogadzirisa zvese zviri munjodzi uye nepasi pekuchengetedza mikaha yemaitiro inoita kuti kushandiswa kugoneke:

1. Isa zvigamba nekukasika: Iva nechokwadi chekuti masisitimu ese eWindows ane zvigadziriso zvazvino zvekuchengetedza zvakaiswa. Isa pamberi pemagumo anoshandiswa nevashandi vanobata nhaurirano dzekunze nemafaira.
2. Ongorora zvigadziriso zvemafaera ekubatana: Ongorora uye dzikamisa kuti ndeapi maapplication akaiswa seagara aripo ezvibati zve .txt uye .log mafaera pane ese bhizinesi, kunyanya pane eukoshi hwepamusoro pekupedzisira.
3. Simbisa kodzero shoma: Bvisa kodzero dzemutungamiriri kubva kumaakaundi evashandisi akajairwa. Kunyangwe RCE ikawaniswa, kodzero dzemushandisi shoma dzinoderedza zvakanyanya kukanganisa kweanorwisa.
4. Deploy advanced endpoint sight:Gadzirisa mhinduro dzepanoperera uye mhinduro (EDR) kuti utarise maitiro eNotepad, kucherekedza kugadzirwa kwemwana zvisina kujairika kana kubatanidza netiweki.
5. Dzidziso yekuziva kwevashandisi: Dzidzisa vashandi kuti nyangwe mafaira ari pachena anogona kuve nechombo, zvichisimbisa kunyunyuta kune hutano kumafaira asina kukumbirwa zvisinei nekuwedzerwa.

Mapuratifomu eBusiness Anhasi Angabatsira Sei Kudzikisa Nzvimbo Yako Yese Yekurwisa?

Kusagadzikana seWindows Notepad RCE inosimbisa chokwadi chakadzama: zvakakamurwa, midziyo yenhaka inogadzira yakakamukana kuchengetedza njodzi. Yese yekuwedzera desktop application inoshanda pane yevashandi workstations inogona kuve vector. Masangano anobatanidza mashandiro ebhizinesi papuratifomu dzechizvino-zvino, dzekare dzinoderedza kuvimba kwadzo nemaapplications akaiswa munzvimbo yeWindows — uye anoderedza nzvimbo yawo yekurwisa panguva iyi.

Mapuratifomu akaita seMewayz, yakazara 207-module business operating system inovimbwa nevashandisi vanodarika 138,000, inoita kuti zvikwata zvigadzirise CRM, kufambiswa kwebasa, e-commerce mashandiro, mapoipi emukati mebrowser, uye kutaurirana kwakachengeteka nevatengi. Kana mabhizinesi akakosha achigara munzvimbo dzakaomeswa dzemakore kwete kuisirwa Windows maapplication emunharaunda, njodzi inounzwa nekusagadzikana senge Notepad RCE inodzikiswa zvakanyanya pakushanda kwezuva nezuva.

Mibvunzo Inowanzo bvunzwa

Ko Windows Notepad ichiri panjodzi here kana Windows Defender yakabatidzwa?
