要点
- CVE-2017-16129 は superagent (superagent project), superagent に影響する深刻度「中」 (CVSS 5.9) の脆弱性です。
- 今後30日間に悪用される確率(EPSS):1.7%(全脆弱性の 77.9% より高い)。
- 対処:3.7.0 以降に更新してください。
概要
Affected versions of superagent do not check the post-decompression size of ZIP compressed HTTP responses prior to decompressing. This results in the package being vulnerable to a ZIP bomb attack, where an extremely small ZIP file becomes many orders of magnitude larger when decompressed.
This may result in unrestrained CPU/Memory/Disk consumption, causing a denial of service condition.
Recommendation
Update to version 3.7.0 or later.
NVD の説明
The HTTP client module superagent is vulnerable to ZIP bomb attacks. In a ZIP bomb attack, the HTTP server replies with a compressed response that becomes several magnitudes larger once uncompressed. If a client does not take special care when processing such responses, it may result in excessive CPU and/or memory consumption. An attacker might exploit such a weakness for a DoS attack. To exploit this the attacker must control the location (URL) that superagent makes a request to.
