Local attackers can pre-create the predictable gitstatus-install.tmp directory to replace the extracted gitstatusd binary, which then executes with the victim's privileges.","cvssScore":6.7,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H","cwes":["CWE-377"],"vendors":[],"products":[],"references":[{"url":"https://github.com/romkatv/gitstatus/commit/5433ecbb9a572d6c92be9feb33642395fccc782b","tags":[]},{"url":"https://github.com/romkatv/powerlevel10k","tags":[]},{"url":"https://github.com/romkatv/powerlevel10k/blob/v1.20.0/gitstatus/install#L255-L256","tags":[]},{"url":"https://github.com/romkatv/powerlevel10k/commit/98bd39fd335e3f9f560e48e5c1957cb2a6a212c4","tags":[]},{"url":"https://github.com/romkatv/powerlevel10k/issues/2972","tags":[]},{"url":"https://www.vulncheck.com/advisories/powerlevel10k-before-1.20.19-insecure-temporary-directory-via-gitstatus-installer","tags":[]}],"exploitRefs":[{"url":"https://github.com/romkatv/gitstatus/commit/5433ecbb9a572d6c92be9feb33642395fccc782b","tags":[]},{"url":"https://github.com/romkatv/powerlevel10k","tags":[]},{"url":"https://github.com/romkatv/powerlevel10k/blob/v1.20.0/gitstatus/install#L255-L256","tags":[]},{"url":"https://github.com/romkatv/powerlevel10k/commit/98bd39fd335e3f9f560e48e5c1957cb2a6a212c4","tags":[]},{"url":"https://github.com/romkatv/powerlevel10k/issues/2972","tags":[]}],"hasPoc":true,"ai":null}
