medium Nessus Plugin ID 235158

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7476-1 advisory.

 It was discovered that Scrapy improperly exposed HTTP authentication

 credentials to request targets, including during redirects. An attacker

 could use this issue to gain unauthorized access to user accounts. This issue only affected Ubuntu 18.04 LTS and Ubuntu 20.04 LTS. (CVE-2021-41125)

 It was discovered that Scrapy did not remove the cookie header during cross-domain redirects. An attacker could possibly use this issue to gain unauthorized access to user accounts. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2022-0577)

 It was discovered that Scrapy inefficiently parsed XML content. An attacker could use this issue to cause a denial of service by sending a crafted XML response. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2024-1892)

 It was discovered that Scrapy did not properly check response size during decompression. An attacker could send a crafted response that would exhaust memory and cause a denial of service. This issue only affected Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2024-3572)

 It was discovered that Scrapy did not remove the authorization header during cross-domain redirects. An attacker could possibly use this issue to gain unauthorized access to user accounts. This issue only affected

 Ubuntu 18.04 LTS, Ubuntu 20.04 LTS, and Ubuntu 22.04 LTS. (CVE-2024-3574)

 It was discovered that Scrapy did not remove the authorization header during redirects that change scheme but remain in the same domain. This issue could possibly be used by an attacker to expose sensitive

 information or to gain unauthorized access to user accounts. (CVE-2024-1968)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected python-scrapy and / or python3-scrapy packages.
