CVE-2018-1797

Status: ModifiedMedium (5.5)—

IBM WebSphere Application Server 7.0, 8.0, 8.5, and 9.0 using Enterprise bundle Archives (EBA) could allow a local attacker to traverse directories on the system. By persuading a victim to extract a specially-crafted ZIP archive containing "dot dot slash" sequences (../), an attacker could exploit this vulnerability to write to arbitrary files on the system. Note: This vulnerability is known as "Zip-Slip". IBM X-Force ID: 149427.

CVSS

Exploitation probability (EPSS)

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).
