Description:
Several vulnerabilities were reported in IBM Lotus Expeditor. A remote user can execute arbitrary code on the target system. A remote user can bypass access controls. A remote user can view files on the target system. IBM Support Assistant is affected.
A remote user can supply a specially crafted URL to exploit a flaw in the Eclipse Help component and view the locations of files [CVE-2012-0186]. The vendor has assigned SPR SAKL7QQG28 to this vulnerability.
A remote user can create a specially crafted DLL file in a directory or on a remote share (e.g., WebDAV, SMB share). When a file is loaded by the target user from the same directory, the application may load the remote user's DLL instead of the intended DLL and execute arbitrary code [CVE-2012-0187]. The code will run with the privileges of the target user. This type of exploit is also known as "binary planting" or "DLL preloading". The vendor has assigned SPR DKLN8K7TEA, RAKA89HPF2, JKAE893E7R and RAKA899QV5 to this vulnerability.
A remote user can supply a specially crafted header value to spoof a localhost request and bypass access controls [CVE-2012-0191]. The vendor has assigned SPR SAKL7QQG28 and MSTO89WRX8 to this vulnerability.
