{"vuid":"VU#730007","idnumber":"730007","name":"Tychon is vulnerable to privilege escalation due to OPENSSLDIR location","keywords":null,"overview":"### Overview\r\n\r\nTychon contains a privilege escalation vulnerability due to the use of an `OPENSSLDIR` variable that specifies a location where an unprivileged Windows user may be able to place files.\r\n\r\n### Description\r\n\r\nTychon includes an OpenSSL component that specifies an `OPENSSLDIR` variable as a subdirectory that my be controllable by an unprivileged user on Windows. Tychon contains a privileged service that uses this OpenSSL component. A user who can place a specially-crafted `openssl.cnf` file at an appropriate path may be able to achieve arbitrary code execution with SYSTEM privileges.\r\n\r\n### Impact\r\nBy placing a specially-crafted `openssl.cnf` in a location used by Tychon, an unprivileged user may be able to execute arbitrary code with SYSTEM privileges on a Windows system with the vulnerable Tychon software installed.\r\n\r\n### Solution\r\n#### Apply an update\r\nThis issue is addressed in Tychon 1.7.857.82\r\n\r\n### Acknowledgements\r\n\r\nThis document was written by Will Dormann.","clean_desc":null,"impact":null,"resolution":null,"workarounds":null,"sysaffected":null,"thanks":null,"author":null,"public":[],"cveids":["CVE-2022-26872"],"certadvisory":null,"uscerttechnicalalert":null,"datecreated":"2022-04-28T13:07:20.600148Z","publicdate":"2022-04-28T13:07:20.456858Z","datefirstpublished":"2022-04-28T13:07:20.607869Z","dateupdated":"2022-04-28T13:07:20.456849Z","revision":1,"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":68}
