VAR-202005-1052
Vulnerability from variot - Updated: 2026-03-09 19:59When using Apache Tomcat versions 10.0.0-M1 to 10.0.0-M4, 9.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54 and 7.0.0 to 7.0.103 if a) an attacker is able to control the contents and name of a file on the server; and b) the server is configured to use the PersistenceManager with a FileStore; and c) the PersistenceManager is configured with sessionAttributeValueClassNameFilter="null" (the default unless a SecurityManager is used) or a sufficiently lax filter to allow the attacker provided object to be deserialized; and d) the attacker knows the relative file path from the storage location used by FileStore to the file the attacker has control over; then, using a specifically crafted request, the attacker will be able to trigger remote code execution via deserialization of the file under their control. Note that all of conditions a) to d) must be true for the attack to succeed. The program implements support for Servlet and JavaServer Page (JSP). The following products and versions are affected: Apache Tomcat 10.0.0-M1 to 10.0.0-M4, 9.0.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54, 7.0.0 to Version 7.0.103. A deserialization flaw exists in Apache Tomcat's use of a FileStore. The highest threat from the vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-9484) The fix for CVE-2020-9484 was incomplete. to 7.0.107 with a configuration edge case that was highly unlikely to be used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to this issue. (CVE-2021-25329).
For the stable distribution (buster), these problems have been fixed in version 9.0.31-1~deb10u2.
We recommend that you upgrade your tomcat9 packages.

1 www-servers/tomcat < 7.0.104:7 >= 7.0.104:7 < 8.5.55:8.5 >= 8.5.55:8.5
Description
Apache Tomcat improperly handles deserialization of files under specific circumstances.
Impact
A remote attacker could possibly execute arbitrary code with the privileges of the process, or cause a Denial of Service condition.
Workaround
There is no known workaround at this time.
Resolution
All Apache Tomcat 7.x users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/tomcat-7.0.104"
All Apache Tomcat 8.x users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-servers/tomcat-8.5.55"

Note that all of conditions a) to d) must be true for the attack to succeed. The program implements support for Servlet and JavaServer Page (JSP). The following products and versions are affected: Apache Tomcat 10.0.0-M1 to 10.0.0-M4, 9.0.0.0.M1 to 9.0.34, 8.5.0 to 8.5.54, 7.0.0 to Version 7.0.103. A deserialization flaw exists in Apache Tomcat\u0027s use of a FileStore. The highest threat from the vulnerability is to data confidentiality and integrity as well as system availability. (CVE-2020-9484)\nThe fix for CVE-2020-9484 was incomplete. to 7.0.107 with a configuration edge case that was highly unlikely to be used, the Tomcat instance was still vulnerable to CVE-2020-9494. Note that both the previously published prerequisites for CVE-2020-9484 and the previously published mitigations for CVE-2020-9484 also apply to this issue. (CVE-2021-25329). \n\nFor the stable distribution (buster), these problems have been fixed in\nversion 9.0.31-1~deb10u2. \n\nWe recommend that you upgrade your tomcat9 packages. \n\nFor the detailed security status of tomcat9 please refer to\nits security tracker page at:\nhttps://security-tracker.debian.org/tracker/tomcat9\n\nFurther information about Debian Security Advisories, how to apply\nthese updates to your system and frequently asked questions can be\nfound at: https://www.debian.org/security/\n\nMailing list: debian-security-announce@lists.debian.org\n-----BEGIN PGP SIGNATURE-----\n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\nbTsyFezxJiAwaa9xozjItZPdIBFP9lG8Txmv1AotH7WV/8dRsOU=\n=E8Ei\n-----END PGP SIGNATURE-----\n. \nThe purpose of this text-only errata is to inform you about the security\nissues fixed in this release. \n\nInstallation instructions are available from the Fuse 7.9.0 product\ndocumentation page:\nhttps://access.redhat.com/documentation/en-us/red_hat_fuse/7.9/\n\n4.
