mpxj is vulnerable to Path Traversal
53
Medium Risk
This Affects:
mpxjTL;DR
MPXJ extracts Primavera P3 PRX and SureTrak STX schedule files into a temporary directory using embedded filenames without checking that the resulting path stays inside that directory. A crafted file can supply names that escape the temp dir (SureTrak STX names are long enough for classic traversal). Before the fix, reading such a file could write to arbitrary filesystem locations. The fix rejects extracted paths that leave the target directory.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and you use MPXJ to read untrusted Primavera P3 PRX or SureTrak STX files.
Background info
