CVE-2023-43643

Impact

There is a potential for a mutation XSS (mXSS) vulnerability in AntiSamy caused by flawed parsing of the HTML being sanitized. To be subject to this vulnerability the preserveComments directive must be enabled in your policy file and also allow for certain tags at the same time. As a result, certain crafty inputs can result in elements in comment tags being interpreted as executable when using AntiSamy's sanitized output.

Patches

Patched in AntiSamy 1.7.4 and later. See important remediation details in the reference given below.

Workarounds

If you cannot upgrade to a fixed version of the library, the following mitigation can be applied until you can upgrade: Manually edit your AntiSamy policy file (e.g., antisamy.xml) by deleting the preserveComments directive or setting its value to false, if present. Also it would be useful to make AntiSamy remove the noscript tag by adding this in your tag definitions under the <tagrules> node (or deleting it entirely if present):

<tag name="noscript" action="remove"/>

As the previously mentioned policy settings are preconditions for the mXSS attack to work, changing them as recommended should be sufficient to protect you against this vulnerability when using a vulnerable version of this library. However, the existing bug would still be present in AntiSamy or its parser dependency (neko-htmlunit). The safety of this workaround relies on configurations that may change in the future and don't address the root cause of the vulnerability. As such, it is strongly recommended to upgrade to a fixed version of AntiSamy.

CVE-2024-23635

Impact

There is a potential for a mutation XSS (mXSS) vulnerability in AntiSamy caused by flawed parsing of the HTML being sanitized. To be subject to this vulnerability the preserveComments directive must be enabled in your policy file. As a result, certain crafty inputs can result in elements in comment tags being interpreted as executable when using AntiSamy's sanitized output.

Patches

Patched in AntiSamy 1.7.5 and later. This is due to parsing behavior in the neko-htmlunit dependency, just by updating to a newer version the issue was solved. See important remediation details in the reference given below.

v1.7.5: Release version 1.7.5

Compare Source

This release addresses the vulnerability documented in GHSA-2mrq-w8pv-5pvq. AntiSamy versions prior to v1.7.5 are subject to mutation XSS (mXSS) vulnerability when preserving comments. - https://www.cvedetails.com/cve/CVE-2024-23635.

In addition, a number of libraries and plugins were upgraded.

Note: The upgrade in the HTML parser may alter outputs compared to 1.7.4 and before. This may impact regression tests that involve AntiSamy if they are too strict when comparing a resulting output with the expected one.

v1.7.4: Release version 1.7.4

Compare Source

This release addresses the vulnerability documented in CVE-2023-43643. AntiSamy versions prior to v1.7.4 are subject to mutation XSS (mXSS) vulnerability when preserving comments. - https://www.cvedetails.com/cve/CVE-2023-43643.

In addition, a number of libraries and plugins were upgraded, including one with a known vulnerability. Specifically, AntiSamy 1.7.4 upgraded to batik-css v1.17 because batik-css:1.16 is subject to https://www.cvedetails.com/cve/CVE-2022-44729.

Note: The upgrade in the HTML parser may alter outputs compared to 1.7.3 and before. This may impact in regression tests that involve AntiSamy if they are too strict when comparing a resulting output with the expected one.

v1.7.3: Release version 1.7.3

Compare Source

This release simply upgrades a number of dependencies, including one with a known CVE. Versions of org.htmlunit:neko-htmlunit prior to 3.0.0 used by AntiSamy 1.7.2 is subject to CVE-2023-26119.
