Pegasystems · Pega Platform · CVE-2017-11355
**Name of the Vulnerable Software and Affected Versions**
PEGA Platform versions 7.2 ML0 and earlier
**Description**
The issue allows remote attackers to inject arbitrary web script or HTML via specific parameters, including the PATH INFO to the main page, the `beanReference` parameter to the JavaBean viewer page, or the `pyTableName` to the System database schema modification page.
**Recommendations**
For PEGA Platform versions 7.2 ML0 and earlier, consider restricting access to the main page, JavaBean viewer page, and System database schema modification page until a fix is available. As a temporary workaround, avoid using the `beanReference` parameter and the `pyTableName` in their respective pages to minimize the risk of exploitation.
