Detection & IOCsextracted from sources · hover to see the quote
- →Exploit requires a BDC model parameter of type Microsoft.BusinessData.Runtime.DynamicType, which triggers deserialization of an arbitrary XmlSerializer stream; monitor SharePoint BDC model uploads for this type string. ↗
- →Successful exploitation spawns child processes cmd.exe and win32calc.exe under the SharePoint application pool worker process (w3wp.exe); alert on w3wp.exe spawning cmd.exe or calc-family processes. ↗
- →Set a breakpoint / monitor for calls to System.Web.UI.ObjectStateFormatter.Deserialize within w3wp.exe on SharePoint servers as an indicator of exploitation in progress. ↗
- →Exploitation path runs through w3wp.exe (SharePoint application pool); monitor this process for anomalous child process creation or unusual outbound network connections. ↗
- →The vulnerability is triggered via a susceptible API endpoint receiving specially-formatted (deserialization payload) input; inspect HTTP requests to SharePoint APIs for malformed/serialized XML payloads. ↗
- →BDC model upload via SharePoint Central Administration or PowerShell is a prerequisite attack step; audit and alert on new BDC model uploads, especially those containing DynamicType parameter definitions. ↗
- ·The detailed exploit walkthrough in the source documents describes CVE-2019-1257 (ZDI-19-812), which is a related but distinct SharePoint deserialization RCE; CVE-2019-1296 shares the same deserialization root cause (unsafe API input / untrusted data deserialization) and the same patch cycle, so detection hints derived from the exploit mechanics are applicable to both. ↗
- ·The vulnerability affects Microsoft SharePoint where APIs are not properly protected from unsafe data input; the security update corrects how SharePoint handles deserialization of untrusted data, so patching is the primary mitigation. ↗
- ·Exploitation is rated 'Exploitation More Likely' for both latest and older software releases by Microsoft, indicating a higher probability of weaponization even though no public exploit or active exploitation was confirmed at time of disclosure. ↗

CVE-2019-1296 [HIGH] Microsoft SharePoint Remote Code Execution Vulnerability
Microsoft SharePoint Remote Code Execution Vulnerability
Description: A remote code execution vulnerability exists in Microsoft SharePoint where APIs aren't properly protected from unsafe data input. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the SharePoint application pool and the SharePoint server farm account.
Exploitation of this vulnerability requires that a user access a susceptible API on an affected version of SharePoint with specially-formatted input.
The security update addresses the vulnerability by correcting how SharePoint handles deserialization of untrusted data.
FAQ: Is the Preview Pane an attack vector for this vulnerability?

[HIGH] September 2019 Patch Tuesday – 79 Vulns, 17 Critical, Remote Desktop Client, SharePoint, Exploited PrivEsc
This month’s Microsoft Patch Tuesday addresses 79 vulnerabilities with 17 of them labeled as Critical. Of the 17 Critical vulns, 8 are for scripting engines and browsers, 4 are for the Remote Desktop Client, and 3 are for SharePoint. In addition, Microsoft has again patched a critical vulnerability in LNK files, along with a vuln in Azure DevOps / TFS. Adobe has also released patches for Flash and Application Manager.
Update: Following Patch Tuesday, Microsoft updated the entries for CVE-2019-1214 and CVE-2019-1215 to remove the “exploited” label.

CVE-2018-1296 hadoop: HDFS Permissive listXAttr Authorization

CVE-2018-1296 [HIGH] CVE-2018-1296 hadoop: HDFS Permissive listXAttr Authorization
CVE-2018-1296 hadoop: HDFS Permissive listXAttr Authorization
HDFS exposes extended attribute key/value pairs during listXAttrs, verifying only path-level search access to the directory rather than path-level read permission to the referent. This affects features that store sensitive data in extended attributes, such as HDFS encryption secrets.
References:
https://seclists.org/oss-sec/2019/q1/91
Discussion:
Mitigation:
If a file contains sensitive data in extended attributes, users and admins need to change the permission to prevent others from listing the directory which contains the file.
