{"vuid":"VU#611276","idnumber":"611276","name":"Computer Associates BrightStor ARCserve Backup LGSERVER.EXE stack buffer overflow","keywords":["Computer Associates","CA","BrightStor","ARCserve Backup","stack overflow","LGSERVER.EXE","TCP port 1900","NGS00403"],"overview":"Computer Associates BrightStor ARCserve Backup contains a stack buffer overflow, which may allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.","clean_desc":"Computer Associates BrightStor ARCserve Backup products come with a service called LGSERVER.EXE. This service listens on ports 2200/tcp and 1900/tcp. The LGSERVER.EXE process fails to properly validate data packets received on port 1900/tcp, which can cause a stack buffer overflow. According to Computer Associates CAID 34993, the following products are affected BrightStor ARCserve: BrightStor ARCserve Backup for Laptops and Desktops r11.1 SP1\nBrightStor ARCserve Backup for Laptops and Desktops r11.1\nBrightStor ARCserve Backup for Laptops and Desktops r11.0\nBrightStor Mobile Backup r4.0\nCA Protection Suites r2: CA Desktop Protection Suite r2\nCA Business Protection Suite r2\nCA Business Protection Suite for Microsoft Small Business Server Standard Edition r2\nCA Business Protection Suite for Microsoft Small Business Server Premium Edition r2\nCA Desktop Management Suite: DMS r11.0\nDMS r11.1\nNote that exploit code for this vulnerability is publicly available.","impact":"A remote, unauthenticated attacker may be able to execute arbitrary code with local SYSTEM privileges or cause a denial-of-service condition on a vulnerable system.","resolution":"Apply an update\nApply an update, as specified in Computer Associates Security Notice. The following fixes are provided: BABLD r11.1 SP2 – SP2 does not contain the vulnerability, there is no fix to apply\nBABLD r11.1 SP1 - QO83833\nBABLD r11.0 - QI85497\nDMS r11.1 - QO85401\nDMS r11.0 - QI85423\nBMB r4.0 - QO85402","workarounds":"Restrict access You may wish to block access to the vulnerable software from outside your network perimeter, specifically by blocking access to the ports used by the Discovery Service (typically 2200/tcp and 1900/tcp). This will limit your exposure to attacks. However, blocking at the network perimeter would still allow attackers within the perimeter of your network to exploit the vulnerability. The use of host-based firewalls in addition to network-based firewalls can help restrict access to specific hosts within the network. It is important to understand your network's configuration and service requirements before deciding what changes are appropriate.","sysaffected":"","thanks":"This vulnerability was disclosed by Computer Associates, who in turn credit NGSS.","author":"This document was written by Will Dormann.","public":["http://supportconnectw.ca.com/public/sams/lifeguard/infodocs/babldimpsec-notice.asp","http://www3.ca.com/securityadvisor/newsinfo/collateral.aspx?cid=97696","http://www3.ca.com/securityadvisor/vulninfo/vuln.aspx?id=34993","http://secunia.com/advisories/23897","http://xforce.iss.net/xforce/xfdb/31704","http://osvdb.org/displayvuln.php?osvdb_id=31593"],"cveids":["CVE-2007-0449"],"certadvisory":"","uscerttechnicalalert":null,"datecreated":"2007-01-31T18:50:55Z","publicdate":"2007-01-23T00:00:00Z","datefirstpublished":"2007-01-31T21:27:40Z","dateupdated":"2007-02-02T20:18:59Z","revision":15,"vrda_d1_directreport":"0","vrda_d1_population":"2","vrda_d1_impact":"3","cam_widelyknown":"20","cam_exploitation":"0","cam_internetinfrastructure":"12","cam_population":"13","cam_impact":"20","cam_easeofexploitation":"11","cam_attackeraccessrequired":"15","cam_scorecurrent":"25.74","cam_scorecurrentwidelyknown":"25.74","cam_scorecurrentwidelyknownexploited":"41.8275","ipprotocol":"tcp","cvss_accessvector":"","cvss_accesscomplexity":"","cvss_authentication":null,"cvss_confidentialityimpact":"","cvss_integrityimpact":"","cvss_availabilityimpact":"","cvss_exploitablity":null,"cvss_remediationlevel":"","cvss_reportconfidence":"","cvss_collateraldamagepotential":"","cvss_targetdistribution":"","cvss_securityrequirementscr":"","cvss_securityrequirementsir":"","cvss_securityrequirementsar":"","cvss_basescore":"","cvss_basevector":"","cvss_temporalscore":"","cvss_environmentalscore":"","cvss_environmentalvector":"","metric":25.74,"vulnote":null}
