The integrated VNC server on port 5900\u002Ftcp of the affected products could allow a remote attacker to execute code with privileged permissions on the system by sending specially crafted network requests to port 5900\u002Ftcp. Please note that this vulnerability is only exploitable if port 5900\u002Ftcp is manually opened in the firewall configuration of network port X130. The security vulnerability could be exploited by an attacker with network access to the affected devices and port. Successful exploitation requires no privileges and no user interaction. The vulnerability could allow an attacker to compromise confidentiality, integrity and availability of the VNC server. At the time of advisory publication no public exploitation of this security vulnerability was known.","A vulnerability has been identified in SINUMERIK 828D V4.7 (All versions \u003C V4.7 SP6 HF1), SINUMERIK 840D sl V4.7 (All versions \u003C V4.7 SP6 HF5), SINUMERIK 840...","2018-12-12T16:29:00.31","2019-10-09T23:33:32.853",8.1,"CVSS:3.0\u002FAV:N\u002FAC:H\u002FPR:N\u002FUI:N\u002FS:U\u002FC:H\u002FI:H\u002FA:H",{"CVSSMetricV31":15,"CVSSMetricV30":16,"CVSSMetricV2":28,"CVSSMetricV40":15},null,[17],{"Source":18,"Type":19,"CVSSData":20,"ExploitabilityScore":26,"ImpactScore":27},"nvd@nist.gov","Primary",{"Version":21,"VectorString":13,"AttackVector":22,"AttackComplexity":23,"PrivilegesRequired":24,"UserInteraction":24,"Scope":25,"ConfidentialityImpact":23,"IntegrityImpact":23,"AvailabilityImpact":23,"BaseScore":12,"BaseSeverity":23,"ExploitCodeMaturity":15,"RemediationLevel":15,"ReportConfidence":15,"TemporalScore":15,"TemporalSeverity":15,"ConfidentialityRequirement":15,"IntegrityRequirement":15,"AvailabilityRequirement":15,"ModifiedAttackVector":15,"ModifiedAttackComplexity":15,"ModifiedPrivilegesRequired":15,"ModifiedUserInteraction":15,"ModifiedScope":15,"ModifiedConfidentialityImpact":15,"ModifiedIntegrityImpact":15,"ModifiedAvailabilityImpact":15,"EnvironmentalScore":15,"EnvironmentalSeverity":15},"3.0","NETWORK","HIGH","NONE","UNCHANGED",2.2,5.9,[29],{"Source":18,"Type":19,"CVSSData":30,"BaseSeverity":23,"ExploitabilityScore":36,"ImpactScore":37,"ACInsufInfo":15,"ObtainAllPrivilege":15,"ObtainUserPrivilege":15,"ObtainOtherPrivilege":15,"UserInteractionRequired":15},{"Version":31,"VectorString":32,"AccessVector":22,"AccessComplexity":33,"Authentication":24,"ConfidentialityImpact":34,"IntegrityImpact":34,"AvailabilityImpact":34,"BaseScore":35,"BaseSeverity":15,"Exploitability":15,"RemediationLevel":15,"ReportConfidence":15,"TemporalScore":15,"CollateralDamagePotential":15,"TargetDistribution":15,"ConfidentialityRequirement":15,"IntegrityRequirement":15,"AvailabilityRequirement":15,"EnvironmentalScore":15},"2.0","AV:N\u002FAC:M\u002FAu:N\u002FC:C\u002FI:C\u002FA:C","MEDIUM","COMPLETE",9.3,8.6,10,0.04593,[38,38,38,38,38,38,38],"High",[42,47,51,54,57,60],{"vendor":43,"product":44,"version":45,"criteria":46,"vulnerable":4},"siemens","sinumerik_828d_v4.7_firmware","*","cpe:2.3:o:siemens:sinumerik_828d_v4.7_firmware:*:*:*:*:*:*:*:*",{"vendor":43,"product":48,"version":49,"criteria":50,"vulnerable":4},"sinumerik_828d_v4.7","-","cpe:2.3:h:siemens:sinumerik_828d_v4.7:-:*:*:*:*:*:*:*",{"vendor":43,"product":52,"version":45,"criteria":53,"vulnerable":4},"sinumerik_840d_sl_v4.7_firmware","cpe:2.3:o:siemens:sinumerik_840d_sl_v4.7_firmware:*:*:*:*:*:*:*:*",{"vendor":43,"product":55,"version":49,"criteria":56,"vulnerable":4},"sinumerik_840d_sl_v4.7","cpe:2.3:h:siemens:sinumerik_840d_sl_v4.7:-:*:*:*:*:*:*:*",{"vendor":43,"product":58,"version":45,"criteria":59,"vulnerable":4},"sinumerik_840d_sl_v4.8_firmware","cpe:2.3:o:siemens:sinumerik_840d_sl_v4.8_firmware:*:*:*:*:*:*:*:*",{"vendor":43,"product":61,"version":49,"criteria":62,"vulnerable":4},"sinumerik_840d_sl_v4.8","cpe:2.3:h:siemens:sinumerik_840d_sl_v4.8:-:*:*:*:*:*:*:*",6,[65,71],{"url":66,"source":67,"tags":68},"http:\u002F\u002Fwww.securityfocus.com\u002Fbid\u002F106185","Securityfocus",[69,70],"Third Party Advisory","VDB Entry",{"url":72,"source":73,"tags":74},"https:\u002F\u002Fcert-portal.siemens.com\u002Fproductcert\u002Fpdf\u002Fssa-170881.pdf","Siemens",[75],"Vendor Advisory",2,[78],{"id":79,"name":80,"description":81,"extendedDescription":82,"status":83,"abstraction":84,"structure":85},"CWE-190","Integer Overflow or Wraparound","The product performs a calculation that can\n         produce an integer overflow or wraparound when the logic\n         assumes that the resulting value will always be larger than\n         the original value.
