The scrapy/scrapy project is vulnerable to XML External Entity (XXE) attacks due to the use of lxml.etree.fromstring for parsing untrusted XML data without proper validation. This vulnerability allows attackers to perform denial of service attacks, access local files, generate network connections, or circumvent firewalls by submitting specially crafted XML data.

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.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The scrapy/scrapy project is vulnerable to XML External Entity (XXE) attacks due to the use of     lxml.etree.fromstring for parsing untrusted XML data without proper validation. This vulnerability allows     attackers to perform denial of service attacks, access local files, generate network connections, or     circumvent firewalls by submitting specially crafted XML data. (CVE-2024-3572)

Note that Nessus relies on the presence of the package as reported by the vendor.

There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - The scrapy/scrapy project is vulnerable to XML External Entity (XXE) attacks due to the use of
    lxml.etree.fromstring for parsing untrusted XML data without proper validation. This vulnerability allows
    attackers to perform denial of service attacks, access local files, generate network connections, or
    circumvent firewalls by submitting specially crafted XML data. (CVE-2024-3572)
