CVE-2017-7549 describes a local privilege escalation vulnerability in instack-undercloud versions 7.2.0, 6.1.0, and 5.3.0, as packaged in various Red Hat OpenStack Platform releases. The flaw stems from insecure temporary file usage in pre-install and security policy scripts, allowing a local attacker to perform a symbolic-link attack and overwrite arbitrary files. With a CVSS score of 6.4 (Medium), exploitation requires local access and high attack complexity, but can lead to high confidentiality impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
