{"vuid":"VU#760767","idnumber":"760767","name":"Macrium Reflect is vulnerable to privilege escalation due to OPENSSLDIR location","keywords":null,"overview":"### Overview\r\n\r\nMacrium Reflect contains a privilege escalation vulnerability due to the use of an `OPENSSLDIR` variable that specifies a location where an unprivileged Windows user can create files.\r\n\r\n### Description\r\n\r\n**CVE-2020-10143**\r\n\r\nMacrium Reflect includes an OpenSSL component that specifies an `OPENSSLDIR` variable as  `C:\\openssl\\`. Macrium Reflect contains a privileged service that uses this OpenSSL component. Because unprivileged Windows users can create subdirectories off of the system root, a user can create the appropriate path to a specially-crafted `openssl.cnf` file to achieve arbitrary code execution with SYSTEM privileges.\r\n\r\n### Impact\r\nBy placing a specially-crafted `openssl.cnf` in the `C:\\openssl\\` directory, an unprivileged user may be able to execute arbitrary code with SYSTEM privileges on a Windows system with the vulnerable Macrium software installed.\r\n\r\n### Solution\r\n#### Apply an update\r\nThis vulnerability is addressed in [Macrium Reflect v7.3.5281](https://updates.macrium.com/reflect/v7/v7.3.5281/details7.3.5281.htm).\r\n\r\n### Acknowledgements\r\nThis vulnerability was reported by Will Dormann of the CERT/CC.\r\n\r\n This document was written by Will Dormann.","clean_desc":null,"impact":null,"resolution":null,"workarounds":null,"sysaffected":null,"thanks":null,"author":null,"public":["https://updates.macrium.com/reflect/v7/v7.3.5281/details7.3.5281.htm"],"cveids":["CVE-2020-10143"],"certadvisory":null,"uscerttechnicalalert":null,"datecreated":"2020-10-26T16:59:05.232152Z","publicdate":"2020-10-26T16:59:04.993541Z","datefirstpublished":"2020-10-26T16:59:05.258914Z","dateupdated":"2020-11-11T13:44:14.288537Z","revision":4,"vrda_d1_directreport":null,"vrda_d1_population":null,"vrda_d1_impact":null,"cam_widelyknown":null,"cam_exploitation":null,"cam_internetinfrastructure":null,"cam_population":null,"cam_impact":null,"cam_easeofexploitation":null,"cam_attackeraccessrequired":null,"cam_scorecurrent":null,"cam_scorecurrentwidelyknown":null,"cam_scorecurrentwidelyknownexploited":null,"ipprotocol":null,"cvss_accessvector":null,"cvss_accesscomplexity":null,"cvss_authentication":null,"cvss_confidentialityimpact":null,"cvss_integrityimpact":null,"cvss_availabilityimpact":null,"cvss_exploitablity":null,"cvss_remediationlevel":null,"cvss_reportconfidence":null,"cvss_collateraldamagepotential":null,"cvss_targetdistribution":null,"cvss_securityrequirementscr":null,"cvss_securityrequirementsir":null,"cvss_securityrequirementsar":null,"cvss_basescore":null,"cvss_basevector":null,"cvss_temporalscore":null,"cvss_environmentalscore":null,"cvss_environmentalvector":null,"metric":null,"vulnote":30}
