  • http://mail-archives.apache.org/mod_mbox/www-announce/202006.mbox/%3Cfd56bc1d-1219-605b-99c7-946bf7bd8ad4@apache.org%3E

 

Tomcat爆出安全漏洞!Spring Cloud/Boot框架多個(gè)版本受影響

翻譯

  • 漏洞名稱:Apache Tomcat HTTP/2 拒絕服務(wù)漏洞
  • 漏洞編號(hào):CVE-2020-11996
  • 嚴(yán)重程度: 重要
  • 軟件提供商: Apache 軟件基金會(huì)

受影響的版本:

  • Apache Tomcat 10.0.0-M1 ~ 10.0.0-M5
  • Apache Tomcat 9.0.0.M1 ~ 9.0.35
  • Apache Tomcat 8.5.0 ~ 8.5.55

漏洞描述:一個(gè)特別制作的 HTTP/2 請(qǐng)求序列,在短短數(shù)秒內(nèi)能導(dǎo)致 CPU 滿負(fù)載率,如果有足夠數(shù)量多的此類請(qǐng)求連接(HTTP/2)并發(fā)放在服務(wù)器上,服務(wù)器可能會(huì)失去響應(yīng)。

如果條件允許,可以通過升級(jí)到Tomcat新版本來解決漏洞。下面為受影響版本對(duì)應(yīng)的安全版本:

  • Apache Tomcat 10.0.0-M6+
  • Apache Tomcat 9.0.36+
  • Apache Tomcat 8.5.56+

02 Spring Cloud / Boot 框架影響

Apache Tomcat HTTP/2 拒絕服務(wù)漏洞也給Spring Cloud / Boot 框架帶來了一定的影響。下面是所有受影響的版本列表,大家可以查看并對(duì)照下自己的代碼,看看是否受到影響。

Spring Cloud Edgware / Spring Boot 1.5.x

  • Spring Cloud [Edgware.RELEASE - Edgware.SR6] 版本受到影響。
  • Spring Boot [1.5.0.RELEASE - 1.5.22.RELEASE] 版本受到影響。

Spring Cloud Finchley / Spring Boot 2.0.x

  • Spring Cloud [Finchley.RELEASE - Finchley.SR4] 版本受到影響。
  • Spring Boot [2.0.0.RELEASE - 2.0.9.RELEASE] 版本受到影響。

Spring Cloud Greenwich / Spring Boot 2.1.x

  • Spring Cloud [Greenwich.RELEASE - Greenwich.SR6] 版本受到影響。
  • Spring Boot [2.1.0.RELEASE - 2.1.14.RELEASE] 版本受到影響。
  • Spring Boot [2.1.15.RELEASE] 版本已修復(fù)。

Spring Cloud Hoxton / Spring Boot 2.2.x

  • Spring Cloud [Hoxton.RELEASE - Hoxton.SR6] 版本受到影響。
  • Spring Boot [2.2.0.RELEASE - 2.2.7.RELEASE] 版本受到影響。
  • Spring Boot [2.2.8.RELEASE] 版本已修復(fù)。

Spring Boot 2.3.x

  • Spring Boot [2.3.0.RELEASE] 版本受到影響。
  • Spring Boot [2.3.1.RELEASE] 版本已修復(fù)。

03 升級(jí)方案

為了避免上述漏洞,現(xiàn)有兩種升級(jí)方案:

直接升級(jí)Spring Boot版本。

手動(dòng)升級(jí)Tomcat版本。

升級(jí) Spring Cloud Edgware / Spring Boot 1.5.x

Edgware無(wú)法通過升級(jí)Spring Boot版本解決問題。=
