Unauthorized modification of stored content in PeopleFinder, SAP security note 1534306

SAP security note 1534306, "Unauthorized modification of stored content in PeopleFinder". Below are the symptom and SAP recommended solution.

Description

Symptom

PeopleFinder can be abused by a malicious user, allowing them to modify application content, persist the modified content without authorization, and potentially obtain authentication information from other legitimate users.

Solution

Apply the appropriate patch for your version of KMC Content Management:

• KMC Content Management 7.00 SP21: Patch 7
• KMC Content Management 7.00 SP22: Patch 3
• KMC Content Management 7.00 SP23: Patch 1
• KMC Content Management 7.01 SP05: Patch 5
• KMC Content Management 7.01 SP06: Patch 4
• KMC Content Management 7.01 SP07: Patch 2
• KMC Content Management 7.01 SP08: Patch 1

Reason and prerequisites

• PeopleFinder results in a stored cross-site scripting issue.
• It can be used to permanently modify displayed content from a website, allowing the malicious user to embed content that is rendered automatically without having to target victims individually.
• Stored cross-site scripting can also be used to steal another user’s authentication information, such as data relating to their current session.
• A malicious user who gains access to this data may use it to impersonate the user and access all information with the same rights as the target user. If an administrator is impersonated, the security of the application may be fully compromised.
