EUVDB-ID: #VU54943
Risk: Low
CVSSv3.1: 6.2 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2013-0248
CWE-ID:
CWE-61 - UNIX Symbolic Link (Symlink) Following
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to a symlink following issue. The application uses the /tmp directory for uploaded files. A local user can create a specially crafted symbolic link to a critical file on the system and overwrite it with privileges of the application.
Successful exploitation of this vulnerability may result in privilege escalation.
MitigationUpdate the affected packages.

EUVDB-ID: #VU5233
Risk: Medium
CVSSv3.1: 8 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H/E:F/RL:O/RC:C]
CVE-ID: CVE-2014-0050
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to cause DoS conditions on the target system.
The weakness exists due to boundary error when handling Content-Type HTTP header for multipart requests. By sending a specially crafted Content-Type header, containing 4092 characters in "boundary" field, a remote attacker can cause the application to enter into an infinite loop.
Successful exploitation of the vulnerability results in denial of service on the vulnerable system.
Note: the vulnerability was being actively exploited.
Update the affected packages.

EUVDB-ID: #VU197
Risk: Medium
CVSSv3.1: 5.9 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:N/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2016-3092
CWE-ID:
CWE-400 - Resource exhaustion
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to cause denial of service conditions on the target system.
