Short explanation
A flaw exists in OpenSCAP due to improper validation of relative file path attributes during Source DataStream (SDS) file decomposition [S0]. This vulnerability allows an attacker to create or modify files without authorization by tricking a user or automated system into decomposing a crafted datastream [S0].
It compromises system integrity by allowing unauthorized file writing or modification outside the intended target directory with the permissions of the executing process [S0].
What should be done?
- Follow the vendor advisory [S0].
Chain of evidence and sources
OpenSCAP uygulamasının Kaynak Veri Akışı dosyalarını ayrıştırırken göreceli dosya yollarını doğrulamaması yol atlama zafiyetine yol açar [S0].
Başarılı istismar, yürütülen sürecin izinleriyle hedef dizin dışında dosya oluşturulmasına veya değiştirilmesine imkân tanır [S0].
Show the technical text from the sources
A flaw was found in OpenSCAP. When decomposing a Source DataStream (SDS) file, the application does not properly validate relative file path attributes, leading to a path traversal vulnerability. An attacker can exploit this flaw by tricking a user or automated system into decomposing a crafted datastream containing directory traversal sequences. Successful exploitation allows unauthorized file creation or modification outside the intended target directory with the permissions of the executing process.
