CVE-2024-39565
Junos OS: J-Web: An unauthenticated, network-based attacker can perform XPATH injection attack against a device.
Что произошло
An Improper Neutralization of Data within XPath Expressions ('XPath Injection') vulnerability in J-Web shipped with Juniper Networks Junos OS allows an unauthenticated, network-based attacker to execute remote commands on the target device. While an administrator is logged into a J-Web session or has previously logged in and subsequently logged out of their J-Web session, the attacker can arbitrarily execute commands on the target device with the other user's credentials. In the worst case, the attacker will have full control over the device. This issue affects Junos OS: * All versions before 21.2R3-S8, * from 21.4 before 21.4R3-S7, * from 22.2 before 22.2R3-S4, * from 22.3 before 22.3R3-S3, * from 22.4 before 22.4R3-S2, * from 23.2 before 23.2R2, * from 23.4 before 23.4R1-S1, 23.4R2.
Что это значит
В источнике описана ошибка безопасности в перечисленных продуктах. Фактический риск зависит от установленной версии, конфигурации и доступности компонента; проверьте условия в первичном бюллетене.
Что делать
1. Проверьте, затронуты ли вы
Соберите инвентаризацию и сравните с таблицей затронутых версий. Эти команды только показывают установленные компоненты и сами по себе не доказывают наличие CVE.
dpkg-query -W -f='${Package} ${Version}\n'rpm -qa --qf '%{NAME}\t%{VERSION}-%{RELEASE}\n'Get-HotFix | Select-Object HotFixID, InstalledOn
2. Установите исправление
The following software releases have been updated to resolve this specific issue: 21.2R3-S8, 21.4R3-S7, 22.2R3-S4, 22.3R3-S3, 22.4R3-S2, 23.2R2, 23.4R1-S1, 23.4R2, 24.2R1, and all subsequent releases.
3. Временные меры
There are no known workarounds for this issue other than disabling J-Web when not in use. Juniper Networks has written an effective countermeasure for this attack at IDP Signature SigPack #3675 onward, released on 07 February 2024. The signature “HTTP:PHP:LAUNCHPAD-CMD-INJ” will identify and block the attack. For best effect, customers may deploy this signature on devices where J-Web is not used.
Methods which may reduce, but not eliminate, the risk for exploitation of these problems, and which does not mitigate or resolve the underlying problem include: • Deploying the appropriate IDP Signature on devices which do not have J-Web enabled which protect the device downstream which requires J-Web to be enabled. • Disabling J-Web and using only alternate options such as Netconf over SSH for device management • Restricting the use of J-Web to low-privileged accounts only In addition to the recommendations listed above, it is good security practice to limit the exploitable attack surface of critical infrastructure networking equipment. Use access lists or firewall filters to limit access to the device only from trusted, administrative networks or hosts.
4. Проверьте следы эксплуатации
Проверьте аномальные входы, новые учётные записи, ошибки и необычные дочерние процессы в затронутом сервисе. Публичные проверенные правила обнаружения не включены в запись; отсутствие сигналов не доказывает отсутствие компрометации.
5. После исправления
- Проверьте фактическую версию и результат установки по бюллетеню.
- При необходимости перезапустите сервисы в согласованное окно.
- Повторите проверку сканером и функциональные проверки.
- Зафиксируйте результат, дату, владельца и оставшийся риск.
