Summary
In Kitodo.Production prior to version 3.9.2, org.kitodo.production.helper.XMLUtils exposes XML parsing helpers that build a JAXP parser with the default, non-secure configuration. An authenticated user uploading an EAD/XML file can trigger XXE injection, leading to local file disclosure and SSRF requests.
Risk Assessment
An authenticated user could read local server files or perform SSRF requests, potentially leading to data leakage or further internal network exploration. This poses a serious risk to confidentiality and integrity.
Recommendation
Upgrade Kitodo.Production to version 3.9.2, which contains the fix. Until patched, restrict EAD/XML file uploads to trusted users.

SEPPmail Secure Email Gateway before 15.1.1 trusts a file path supplied in externally provided Large File Transfer attachment metadata. An unauthenticated remote sender can cause the mail-processing worker to disclose, move, or delete an accessible regular file when LFT is enabled and the message reaches an affected secure-mail processing path. The validated workers ran as root.

SEPPmail Secure Email Gateway before 15.1.1 can evaluate attacker-influenced replacement text as Perl code in sender or recipient replacement rules. An unauthenticated remote sender can execute operating-system commands in the mail-processing worker context when an active rule uses message-derived replacement data and its search condition matches. The validated worker context was root.

A vulnerability was found in Qihoo 360 devices (models D621-2, D603-2, D600-2, D619, D606-6 and D706 up to 6.4.9) in the verify_sign function of fs2/bin/iscm responsible for firmware signature verification. Manipulating the sign argument leads to improper verification of cryptographic signatures. The attack can be launched remotely and the exploit has been publicly disclosed.
Original NVD description (English source)
Kitodo.Production is a workflow management tool for mass digitization and is part of the Kitodo Digital Library Suite. Prior to version 3.9.2, org.kitodo.production.helper.XMLUtils exposes several XML parsing helpers that construct a JAXP parser with the default, non-secure configuration. The methods parseXMLString(String), getNumberOfEADElements(String, String) and checkIfXmlIsWellFormed(String) build a DocumentBuilderFactory / XMLInputFactory / SAXParserFactory via newInstance() and parse the attacker-supplied string without disabling DOCTYPE declarations or external entity resolution. These helpers sit directly on the EAD-import path: an authenticated user who uploads an EAD/XML file through the "Create process" file-upload dialog has the uploaded bytes parsed by these methods. A crafted document with an external entity therefore yields XML External Entity (XXE) injection: local file disclosure and outbound SSRF requests from the server. This issue has been patched in version 3.9.2.
