This vulnerability is due to incorrectly implemented Java deserialization. An attacker can exploit this vulnerability by sending malicious data to the affected server. This can be done by sending HTTP requests with crafted serialized data. A successful exploit can lead to arbitrary code execution. Bitbucket Server versions 5.14.0 and later before 7.6.14, 7.7.0 and later prior to 7.17.6, 7.18.0 and later prior to 7.18.4, 7.19.0 and later prior to 7.19.4, and 7.20.0 allow remote attackers to execute arbitrary code via deserialization of malicious data. This is due to incorrect handling of Java deserialization. This vulnerability is specific to Atlassian Bitbucket Server. It does not affect Atlassian Bitbucket Cloud or Atlassian Bitbucket Data Center. This issue was resolved in version 7.20.0. Shipped version 7.20.0. SharedSecretClusterAuthenticator in Atlassian Bitbucket Data Center versions 7.18.0 and later prior to 7.18.4, 7.19.0 and later prior to 7.19.4, and 7.20.0 allow remote attackers to execute arbitrary code via deserialization of malicious data. This is due to incorrect handling of Java deserialization. This vulnerability was disclosed by Dawid Golunski in the “Apache Struts CVE-2018-

Vulnerability present in version prior to 5.14.0

This vulnerability is due to an error with correctly implemented Java deserialization. An attacker can exploit this vulnerability by sending malicious data to the affected server. This can be done by sending HTTP requests with crafted serialized data. A successful exploit can lead to arbitrary code execution. Bitbucket Server versions 5.14.0 and later before 7.6.14, 7.7.0 and later prior to 7.17.6, 7.18.0 and later prior to 7.18.4, 7.19.0 and later prior to 7.19.4, and 7

Description

The vulnerability is due to incorrectly implemented Java deserialization. An attacker can exploit this vulnerability by sending malicious data to the affected server. This can be done by sending HTTP requests with crafted serialized data. A successful exploit can lead to arbitrary code execution. Bitbucket Server versions 5.14.0 and later before 7.6.14, 7.7.0 and later prior to 7.17.6, 7.18.0 and later prior to 7.18.4, 7.19.0 and later prior to 7.19.4, and 7.20

deserialization of malicious data
This vulnerability is specific to Atlassian Bitbucket Server (Buckets), provided by and used in Atlassian Bitbucket Cloud (Cloud) or Atlassian Bitbucket Data Center (Data Center). It does not affect Atlassian Bitbucket Cloud or Atlassian Bitbucket Data Center, which are Azure Cloud Services or Microsoft Azure SQL Database respectively that use different software for authentication and administration than Buckets for the purpose of security control and separation of duties among administrators in a multi-tenant environment .

Vulnerability Description:

Bitbucket Server versions 5.14.0 and later before 7.6.14, 7.7.0 and later prior to 7.17.6, 7.18.0 and later prior to 7.18.4, 7.19.0 and later prior to 7.19.4, and 7.20.0 allow remote attackers to execute arbitrary code via deserialization of malicious data

Vulnerability Discovery in Bitbucket Server CVE-2018-2022

This vulnerability is due to a flaw in the Apache Struts library. An attacker could exploit this by sending malicious data to the affected server. This can be done by sending HTTP requests with crafted serialized data. A successful exploit could lead to arbitrary code execution. Bitbucket Server versions 7.6.14, 7.7.0 and later before 7.17.6, 7.18.4 and later prior to 7.18.5, 7.19.5 and later prior to 7.19.4, and 7.20) allow remote attackers to execute arbitrary code via deserialization of malicious data . This is due to incorrect handling of Java deserialization . This vulnerability was disclosed by Dawid Golunski in the “Apache Struts CVE-2018-
