When some conditions in the user-controlled input buffer are not met, the driver writes an error code (0x2000001A) to a user-controlled address. Also, note that all the aforementioned IOCTLs use transfer type METHOD_NEITHER, which means that the I\u002FO manager does not validate any of the supplied pointers and buffer sizes. So, even though the driver checks for input\u002Foutput buffer sizes, it doesn't validate if the pointers to those buffers are actually valid. So, we can supply a pointer for the output buffer to a kernel address space address, and the error code will be written there. We can take advantage of this condition to modify the SEP_TOKEN_PRIVILEGES structure of the Token object belonging to the exploit process and grant SE_DEBUG_NAME privilege. This allows the exploit process to interact with higher privileged processes running as SYSTEM and execute code in their security context.","Sophos SafeGuard Enterprise before 8.00.5, SafeGuard Easy before 7.00.3, and SafeGuard LAN Crypt before 3.95.2 are vulnerable to Local Privilege Escalation v...","2018-07-09T18:29:00.827","2019-10-03T00:03:26.223",7.8,"CVSS:3.0\u002FAV:L\u002FAC:L\u002FPR:L\u002FUI:N\u002FS:U\u002FC:H\u002FI:H\u002FA:H",{"CVSSMetricV31":15,"CVSSMetricV30":16,"CVSSMetricV2":29,"CVSSMetricV40":15},null,[17],{"Source":18,"Type":19,"CVSSData":20,"ExploitabilityScore":27,"ImpactScore":28},"nvd@nist.gov","Primary",{"Version":21,"VectorString":13,"AttackVector":22,"AttackComplexity":23,"PrivilegesRequired":23,"UserInteraction":24,"Scope":25,"ConfidentialityImpact":26,"IntegrityImpact":26,"AvailabilityImpact":26,"BaseScore":12,"BaseSeverity":26,"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","LOCAL","LOW","NONE","UNCHANGED","HIGH",1.8,5.9,[30],{"Source":18,"Type":19,"CVSSData":31,"BaseSeverity":26,"ExploitabilityScore":36,"ImpactScore":37,"ACInsufInfo":4,"ObtainAllPrivilege":15,"ObtainUserPrivilege":15,"ObtainOtherPrivilege":15,"UserInteractionRequired":15},{"Version":32,"VectorString":33,"AccessVector":22,"AccessComplexity":23,"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:L\u002FAC:L\u002FAu:N\u002FC:C\u002FI:C\u002FA:C","COMPLETE",7.2,3.9,10,0.00601,[38,38,38,38,38,38,38],"High",[42,47,50,53,57,59,62,64,66,69,73,76],{"vendor":43,"product":44,"version":45,"criteria":46,"vulnerable":4},"sophos","safeguard_easy_device_encryption_client","6.00","cpe:2.3:a:sophos:safeguard_easy_device_encryption_client:6.00:*:*:*:*:*:*:*",{"vendor":43,"product":44,"version":48,"criteria":49,"vulnerable":4},"6.10","cpe:2.3:a:sophos:safeguard_easy_device_encryption_client:6.10:*:*:*:*:*:*:*",{"vendor":43,"product":44,"version":51,"criteria":52,"vulnerable":4},"7.00","cpe:2.3:a:sophos:safeguard_easy_device_encryption_client:7.00:*:*:*:*:*:*:*",{"vendor":43,"product":54,"version":55,"criteria":56,"vulnerable":4},"safeguard_enterprise_client","5.60.3","cpe:2.3:a:sophos:safeguard_enterprise_client:5.60.3:vs-nfd:*:*:*:*:*:*",{"vendor":43,"product":54,"version":45,"criteria":58,"vulnerable":4},"cpe:2.3:a:sophos:safeguard_enterprise_client:6.00:*:*:*:*:*:*:*",{"vendor":43,"product":54,"version":60,"criteria":61,"vulnerable":4},"6.00.1","cpe:2.3:a:sophos:safeguard_enterprise_client:6.00.1:*:*:*:*:*:*:*",{"vendor":43,"product":54,"version":48,"criteria":63,"vulnerable":4},"cpe:2.3:a:sophos:safeguard_enterprise_client:6.10:*:*:*:*:*:*:*",{"vendor":43,"product":54,"version":51,"criteria":65,"vulnerable":4},"cpe:2.3:a:sophos:safeguard_enterprise_client:7.00:*:*:*:*:*:*:*",{"vendor":43,"product":54,"version":67,"criteria":68,"vulnerable":4},"8.00","cpe:2.3:a:sophos:safeguard_enterprise_client:8.00:*:*:*:*:*:*:*",{"vendor":43,"product":70,"version":71,"criteria":72,"vulnerable":4},"safeguard_lan_crypt_client","3.90.1","cpe:2.3:a:sophos:safeguard_lan_crypt_client:3.90.1:ts:*:*:*:*:*:*",{"vendor":43,"product":70,"version":74,"criteria":75,"vulnerable":4},"3.90.2","cpe:2.3:a:sophos:safeguard_lan_crypt_client:3.90.2:*:*:*:*:*:*:*",{"vendor":43,"product":70,"version":77,"criteria":78,"vulnerable":4},"3.95.1","cpe:2.3:a:sophos:safeguard_lan_crypt_client:3.95.1:*:*:*:*:*:*:*",12,[81,87,93],{"url":82,"source":83,"tags":84},"http:\u002F\u002Fseclists.org\u002Ffulldisclosure\u002F2018\u002FJul\u002F20","Seclists",[85,86],"Mailing List","Third Party Advisory",{"url":88,"source":89,"tags":90},"https:\u002F\u002Fcommunity.sophos.com\u002Fkb\u002Fen-us\u002F131934","Sophos",[91,92],"Patch","Vendor Advisory",{"url":94,"source":95,"tags":96},"https:\u002F\u002Flabs.nettitude.com\u002Fblog\u002Fcve-2018-6851-to-cve-2018-6857-sophos-privilege-escalation-vulnerabilities\u002F","Nettitude",[97,98,86],"Exploit","Technical Description",3,[101],{"id":102,"name":103,"description":104,"extendedDescription":105,"status":106,"abstraction":107,"structure":108},"CWE-119","Improper Restriction of Operations within the Bounds of a Memory Buffer","The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary.
